[System]
You are participating in Blender-Bench, a public benchmark where AI models complete the same Blender task.

Your result will be compared head-to-head with another model. Anyone on the internet can vote based on two equally important published views: a 2D rendered presentation and an interactive 3D scene exported to GLB. Treat neither view as optional; make the result clear and compelling in both.

Complete the request as well as you can. The benchmark does not prescribe a workflow or visual style; use whichever Blender techniques you consider appropriate. Make the important requirements evident in the published result, save a complete scene, and present the work clearly in every requested output.

The 2D presentation is rendered by the benchmark from your saved scene using Cycles at 1536 x 1536, 64 samples, denoising enabled, and GPU acceleration when available with a CPU fallback. It is the native-fidelity view of the Blender scene, so you may use Blender's full feature set. Preview and validate your materials, lighting, color management, and camera composition in Cycles, and do not rely on EEVEE-only effects for the final appearance.

The interactive 3D view is a best-effort GLB export containing geometry, compatible materials, the contestant camera, and supported lights. Because glTF cannot represent every Blender feature, native effects such as particles, hair or curves, volumes, simulations, and some procedural geometry may appear only in the 2D render. The benchmark may also generate a separate preview GLB by baking supported procedural material inputs to textures; this does not convert unsupported geometry or guarantee exact parity with Blender. When practical, keep the core form and scene readable in the 3D view while using the 2D presentation to show native Blender features faithfully.

## Harness Instructions

You are operating Blender through the provided tools. Tool calls execute one at a time, in the order you issue them, against a single live Blender instance — each call sees the state left by the previous one, and issuing several calls in one message gains no parallelism. The scene starts empty. Build what the user's prompt asks for in the current scene. Work step by step and verify your own work.

You are building a real three-dimensional scene, and evaluators judge the whole scene and your final render side by side — an interactive 3D view and a benchmark-generated 360° camera orbit rendered in Cycles from your saved scene appear next to your presentation render, so forms that only read correctly from one angle will show. Build genuine 3D first, then present it well: before you finish, set up a camera and lighting to frame a single, well-composed presentation image of your result — a good scene that happens to have a well-placed camera and lights. The final benchmark capture overrides the scene render settings and renders in Cycles at 1536x1536, 64 samples, with denoising and GPU acceleration (CPU fallback). Preview and validate materials, lighting, color management, and composition in Cycles; do not rely on EEVEE-only effects. Use whatever Blender features best serve the result; a best-effort GLB export is also provided for interactive inspection, and features glTF cannot represent are not expected to survive it. When you are finished, reply with the single word DONE and no tool calls.

## Task

Complete the following Blender task:

<task>

A warm wooden cabin beside a pond, with a stone chimney, a small dock, and a few trees.

</task>

[Tool]
{
  "status": "ok",
  "result": {
    "version": "5.1.0",
    "h_cabin": 0.55,
    "h_pond_center": -1.188,

    ],
    "objects": 2
  },
  "stdout": "{'version': '5.1.0', 'h_cabin': 0.55, 'h_pond_center': -1.188, 'shore_cabin_side': 0.194, 'extent': (-34.0, 34.0, -34.0, 34.0), 'objects': 2}\n"
}

[Assistant] Blender 5.1, good. Terrain and pond water are in place. Now I'll build the log cabin: walls, floor, gable roof, stone chimney, door, windows, and front steps.

[Assistant] The API uses `radius1`/`radius2`. Fixing and rerunning the cabin build.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cabin built, objects: 68\n"
}

[Assistant] Cabin structure is built (68 objects). Now I'll create the materials: log wood with grain, roof planks, stone, glass, water, and grass ground.

[Assistant] The screenshot tool returns no image data, so I'll verify visually via a rendered PNG and inspect it numerically. Let me first analyze the rendered image with Python to check composition and brightness.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "exists True size 2289161\ndims 1536 1536 mean RGB [0.416 0.445 0.28 ]\nmin/max 0.007843137718737125 0.6823529601097107\ncenter [0.125 0.204 0.055]\ntop band mean [0.535 0.555 0.364]\nbottom band mean [0.412 0.406 0.29 ]\n"
}

[Assistant] The render is fairly bright overall. To see the actual image, let me save a small version and check with the screenshot API, or better — verify the scene structure and check for common issues (e.g., geometry clipping, materials). First, let me confirm which objects are visible and check the cabin alignment.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "counts {'MESH': 256, 'LIGHT': 3, 'CAMERA': 1}\nCabinFloor loc <Vector (-4.0000, 1.0000, 0.4700)> dim <Vector (4.2000, 3.2000, 0.1750)>\nRoof loc <Vector (0.0000, 0.0000, 0.0000)> dim <Vector (10.2000, 7.8000, 2.5600)>\nChimney loc <Vector (-4.5000, -0.6000, 3.6000)> dim <Vector (0.5500, 0.6000, 3.2000)>\nPondWater loc <Vector (0.0000, 0.0000, 0.0000)> dim <Vector (14.0000, 14.0000, 0.0000)>\nDoor loc <Vector (0.0800, 2.2000, 1.6700)> dim <Vector (0.0600, 0.8500, 1.2500)>\nAwning loc <Vector (0.6000, 2.2000, 3.0500)> dim <Vector (0.5000, 1.6600, 0.0600)>\npond dims <Vector (14.0000, 14.0000, 0.0000)>\ncam dir <Vector (-0.7189, 0.6942, -0.0349)>\ncam loc <Vector (11.0000, 7.5000, 1.7500)>\n"
}

[Assistant] The camera is looking roughly at the cabin area. Let me actually view the rendered output by copying it into the Blender image editor and reading it via the screenshot, or better — I'll analyze the render more carefully for problems. The render shows greenish center (0.125, 0.204, 0.055 — likely foliage/grass), so the cabin may be visible but let me check the actual frame by examining a downscaled ASCII visualization of the luminance.

}

[Assistant] The ASCII map is hard to interpret. Let me open the render in an Image Editor and screenshot that area to actually see it.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "switched area\nimage CheckRender <bpy_int[2], Image.size>\n"
}

[Assistant] The screenshot tool returns no data (likely not supported in this environment). I'll rely on numeric analysis plus targeted render-region checks. Let me check where the cabin lands in the frame and whether the pond/cabin are framed well.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cabin_front_center -> (-2.062, 0.009)\ncabin_ridge -> (-2.116, 0.654)\ncabin_left -> (-1.677, 0.053)\ncabin_right -> (-3.117, 0.093)\npond_center -> None\npond_far -> None\npond_near -> None\ndock_start -> None\ndock_end -> None\ndoor -> (-2.319, -0.0)\nchimney -> (-2.631, 0.546)\ntree_back_l -> (-0.991, 0.18)\ntree_back_r -> (-0.819, 0.35)\n"
}

[Assistant] The cabin is at NDC x≈-2 to -3, which is far off-screen to the left (visible range -1..1). My projection math might be off due to focal length handling, but the camera clearly isn't framing the scene well — pond points returned None (behind camera or outside). Let me reposition the camera to properly frame the cabin, pond, and dock from a good angle.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cam loc <Vector (13.5000, 6.5000, 2.6000)> rot <Euler (x=1.5708, y=-0.0000, z=1.9720), order='XYZ'>\ncabin_front_center -> (-2.062, 0.009)\ncabin_ridge -> (-2.116, 0.654)\ncabin_left -> (-1.677, 0.053)\ncabin_right -> (-3.117, 0.093)\npond_center -> None\npond_far -> None\npond_near -> None\ndock_start -> None\ndock_end -> None\ndoor -> (-2.319, -0.0)\nchimney -> (-2.631, 0.546)\ntree_back_l -> (-0.991, 0.18)\ntree_back_r -> (-0.819, 0.35)\n"
}

[Assistant] My manual projection is suspect. Let me use Blender's own `world_to_camera_view` to check framing.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cabin_front_center -> (0.613, 0.436)\ncabin_ridge -> (0.613, 0.73)\ncabin_left_corner -> (0.529, 0.47)\ncabin_right_corner -> (0.759, 0.448)\npond_center -> (-0.66, 0.207)\npond_far -> (-0.97, 0.264)\npond_near -> (-0.153, 0.113)\ndock_start -> (-0.148, 0.325)\ndock_end -> (-1.618, 0.253)\ndoor -> (0.609, 0.417)\nchimney -> (0.53, 0.645)\ntree_back_l -> (0.952, 0.579)\ntree_back_r -> (1.14, 0.67)\n"
}

[Assistant] The cabin is on the right side (x≈0.6), pond on the left, but the dock extends off-screen left, and the cabin is too far right. Let me adjust the camera to get a balanced composition: cabin centered-ish, pond + dock visible in foreground, trees framing.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cabin_front_center -> (0.621, 0.432)\ncabin_ridge -> (0.621, 0.746)\ncabin_left_corner -> (0.531, 0.468)\ncabin_right_corner -> (0.777, 0.444)\npond_center -> (-0.743, 0.186)\npond_far -> (-1.075, 0.247)\npond_near -> (-0.2, 0.085)\ndock_start -> (-0.194, 0.312)\ndock_end -> (-1.769, 0.235)\ndoor -> (0.616, 0.411)\nchimney -> (0.532, 0.655)\ntree_back_l -> (0.984, 0.585)\ntree_back_r -> (1.186, 0.682)\n"
}

[Assistant] Still off. The dock is off-screen left and the cabin pushed right. I need to move the camera further away/back so both fit. Let me try a wider, more frontal composition.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cabin_front_center -> (0.631, 0.415)\ncabin_ridge -> (0.63, 0.807)\ncabin_left_corner -> (0.577, 0.454)\ncabin_right_corner -> (0.734, 0.442)\npond_center -> (-1.056, 0.174)\npond_far -> (-1.207, 0.247)\npond_near -> (-0.756, 0.028)\ndock_start -> (-0.422, 0.295)\ndock_end -> (-1.948, 0.261)\ndoor -> (0.543, 0.398)\nchimney -> (0.536, 0.688)\ntree_back_l -> (1.137, 0.609)\ntree_back_r -> (1.181, 0.815)\n---\ncabin_front_center -> (0.618, 0.424)\ncabin_ridge -> (0.617, 0.776)\ncabin_left_corner -> (0.569, 0.458)\ncabin_right_corner -> (0.71, 0.448)\npond_center -> (-0.901, 0.206)\npond_far -> (-1.036, 0.272)\npond_near -> (-0.631, 0.075)\ndock_start -> (-0.33, 0.316)\ndock_end -> (-1.703, 0.285)\ndoor -> (0.539, 0.409)\nchimney -> (0.532, 0.669)\ntree_back_l -> (1.073, 0.598)\ntree_back_r -> (1.113, 0.784)\n"
}

[Assistant]
The issue is clear now: the dock runs off to the left far out of frame, and the pond center is far left too. The cabin occupies only the right portion. I need to rethink the composition: move the camera to the east, looking west, so the cabin is left/center and the pond extends right, or better, reposition the dock so it points toward the camera.

The dock currently extends from shore (4.6,-4.9) toward (11.6,-12) — away from the camera position. The camera at (10-16, 8-11) is north of the dock. The dock should point toward the viewer. Let me rotate the dock to point southeast toward the camera-side shore, and place the camera south of the pond looking north at the cabin.

Let me reconsider the whole layout: cabin at (-4,1), pond centered (8,-7). The pond's near shore to the camera should be its south side (y=-13). If the camera is at (6, -16) looking north, the cabin would be behind the pond. Better: camera east of pond at (15, -2) looking west-northwest toward cabin (-4,1). The dock from shore toward the pond center — from (4.6,-4.9) toward (8,-7) — that's toward the pond center, which is toward the west from the camera. That would point mostly away.

Actually, for a classic composition: cabin on the left/center, pond in front stretching to the right, dock reaching from the shore toward the viewer/camera. Camera positioned south-east of the pond, e.g., (10,-10), looking northwest at cabin (-4,1). Then the pond is in the middle foreground, the dock from (4.6,-4.9) extending southwest toward the camera would be visible.

The dock direction (0.70,-0.71) normalized points from shore (4.6,-4.9) to (11.6,-12.0). That's pointing southeast. A camera at (10,-10) is roughly southeast of the shore — so the dock would point somewhat toward the camera.

Let me set the camera at (11, -9, 2.5), target (-3, 1, 2.5). Check the projection.The dock is pointing away from my camera. Let me place the camera south of the pond looking northwest, so the dock points toward the viewer and the pond fills the foreground.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cabin_front_center -> (0.634, 0.471)\ncabin_ridge -> (0.636, 0.737)\ncabin_left_corner -> (0.592, 0.516)\ncabin_right_corner -> (0.7, 0.457)\npond_center -> (-0.328, 0.298)\npond_far -> (-0.529, 0.353)\npond_near -> (-0.024, 0.215)\ndock_start -> (-0.004, 0.376)\ndock_end -> (-0.83, 0.345)\ndoor -> (0.583, 0.438)\nchimney -> (0.569, 0.664)\ntree_back_l -> (0.983, 0.609)\ntree_back_r -> (0.925, 0.6)\n"
}

[Assistant]
Better — pond is now left-center, dock visible from (0, 0.38) to (-0.83, 0.35). But the cabin is still far right (x≈0.63) and the dock end at x=-0.83 is near the left edge. I want the cabin more central and the dock clearly in the foreground. The cabin is at x≈0.63, pond center at -0.33 — the whole scene spans -0.85 to 0.98.

Let me pull the camera back and shift the aim left/down so the cabin sits around x=0.55 and the dock sweeps from center toward the lower-left, with pond filling the bottom.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cabin_front_center -> (0.499, 0.451)\ncabin_ridge -> (0.499, 0.756)\ncabin_left_corner -> (0.234, 0.485)\ncabin_right_corner -> (0.834, 0.467)\npond_center -> (0.047, -0.34)\npond_far -> (-5.71, -2.167)\npond_near -> (1.181, 0.02)\ndock_start -> (0.307, 0.188)\ndock_end -> (5.196, 3.22)\ndoor -> (0.726, 0.431)\nchimney -> (0.388, 0.677)\ntree_back_l -> (0.606, 0.596)\ntree_back_r -> (1.192, 0.619)\n"
}

[Assistant]
Now the cabin spans x 0.23–0.83 (center ~0.53), pond center at (0.05,-0.34), dock start (0.31,0.19) but dock end goes off to (5.2,3.2) — that means the dock extends toward the upper right, away from the camera (because from this angle, the dock direction points away). The pond near shore at y=0.02 is at the bottom.

Wait — the dock end at (5.2, 3.2) is far off-screen. That means the dock points away from the camera toward the pond's far side. That's wrong for the composition. The dock should point from the shore INTO the pond — which is what it does geometrically — but from the camera's viewpoint, the pond's far side is behind/right.

Actually looking at the layout: the pond is at (8,-7), the dock goes from (4.6,-4.9) toward (11.6,-12). The camera is at (14.5,-6). The dock is to the left of the camera. From the camera, the dock's far end (11.6,-12) is further left AND further away (more negative y, farther from camera at y=-6). So it should project toward the left... but it shows x=5.2? That suggests my projection is inconsistent — the dock end is beyond the pond far edge.

Let me stop guessing and reconsider: The real problem is the dock is oriented the wrong way for a camera on the south side. I should rotate the dock to point from the shore toward the pond's near side (south), i.e., from (4.6,-4.9) toward (4.6,-10) — toward the camera at (14.5,-6) roughly. Then from the camera, the dock would lead from the shore toward the viewer, appearing in the foreground.

Let me rotate the dock direction to point toward the camera-side (south-southwest). The pond edge nearest the camera is around (8,-13). The shore near the dock start is (4.6,-4.9). A dock from (4.6,-4.9) toward (5.5,-9) would point south, into the pond, toward the camera.

Actually the dock should extend from the shore INTO the pond. The pond center is at (8,-7). The dock at (4.6,-4.9) extending toward (8,-7) would reach the pond center — but that's mostly east. From camera (14.5,-6) looking at cabin (-3.5,1), the pond center (8,-7) projects near center-bottom. A dock pointing from (4.6,-4.9) toward (8,-7) — its far end would be near the pond center, which is in the lower middle of the frame. That would look great: the dock juts into the pond toward the camera.

The current dock goes toward (11.6,-12) which is beyond the pond's far south-west edge — wrong, it goes past the pond. I should rebuild the dock to point from the shore toward the pond center.

Let me rebuild the dock with direction from (4.6,-4.9) toward pond center (8,-7), length ~7, so it ends around (7,-6.4).

}

[Assistant]
Now the dock end at (-1.48,-0.89) is off-screen bottom-left, meaning the dock still extends too far left. The dock start is at (0.18,0.21) but it runs past the pond's near edge. The dock is 7.5 long pointing toward pond center; the pond center is at (0.18,-0.17)... wait no, the pond center projects to (-0.18,-0.17), and the dock end (-1.48,-0.89) is beyond the pond center — because the dock extends past the pond center toward the far edge.

The dock from (4.6,-4.9) toward (8,-7) at length 7.5 ends at (10.98,-8.84) — that's beyond the pond center (8,-7), near the pond's far edge (13,-12). The dock is too long and crosses the whole pond. I should shorten it to ~4.5 so it ends around (7.2,-6.3), just inside the pond near the shore, giving a nice jutting dock.

}

[Assistant] Now the dock spans from (0.18, 0.21) to (-0.29, -0.10) — nicely in the lower-center-left of the frame, leading into the pond. Cabin at (0.49, 0.45) with ridge at 0.74. Let me now render a test and analyze the composition.

[Assistant] The ASCII map is rotated (64 rows shown as columns), but I can see the cabin area (warm 'W' block) and a large bright pond region. Let me verify by sampling pixels at the projected locations of key objects.

}

[Assistant] The cabin is visible (warm wood tones at center), but the pond center and dock mid are off-screen — the pond is mostly below the frame. The current camera is too low/close, and the dock is at the bottom edge. I need a higher, more pulled-back camera to capture the pond fully with the dock visible. Let me adjust.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cabin_ridge -> (0.49, 0.717)\ncabin_center -> (0.49, 0.457)\ncabin_left -> (0.281, 0.49)\ncabin_right -> (0.762, 0.466)\npond_center -> (-0.118, -0.109)\npond_near -> (0.862, 0.082)\npond_far -> (-2.362, -0.546)\ndock_start -> (0.209, 0.262)\ndock_end -> (0.043, 0.133)\ntree_back_l -> (0.613, 0.586)\ntree_back_r -> (1.082, 0.597)\n"
}

[Assistant]
Still the pond center is below frame (y<0). The pond's near shore is at (0.86, 0.08) — right at the bottom edge. The problem: the pond sits mostly below the camera's view because the camera is positioned too far north (y=-4) and the pond center is at (8,-7), far south. The camera at y=-4 looking toward (-2,-1) means the pond is behind/below.

Let me reposition the camera to be south-east of the pond, looking north-west. That way the pond is in front (between camera and cabin).

        Includes type, transforms, parent, children, modifiers, constraints,
        materials, visibility, data-block name, and collections.

Name

get_object_detail_summaryArguments

        Return the scene's collection hierarchy and their objects.

        Each collection lists its objects (name, type, parent, data name,
        selection, visibility) and nested child collections.

get_objects_summaryArguments

        Return the Blender Python API docs for *identifier*, or list
        modules matching a trailing-``*`` discovery pattern.

        *identifier* should be a fully-qualified Python name (e.g.
        ``bpy.app`` or ``bpy.types.Scene.frame_current``).
        The trailing-``*`` forms are supported as discovery entry-points:

        - ``*`` enumerates the top-level modules (``bpy``, ``bmesh``,
          ``mathutils``, ``gpu``, ...).
        - ``X.*`` enumerates the direct-child identifiers under the
          *X* namespace (``bpy.*`` -> ``bpy.app``, ``bpy.context``, ...).

        Both return a ``namespace`` response even when ``X.rst`` would
        otherwise resolve to ``exact``; the ``.*`` form lets an agent
        force the child listing.

        The response always carries ``kind``, ``found``, and ``identifier``.
        The remaining keys depend on ``kind``:

        - ``"exact"`` (``found=True``): ``<identifier>.rst`` was read.
          Extra keys: ``content`` (RST text), ``examples``. When the
          file exceeds 32 KB, ``content`` is replaced with a dot-point
          summary of the file's top-level definitions (prefixed by a
          header noting the truncation) and ``examples`` is empty -
          re-query individual members for their rendered blocks.
        - ``"namespace"`` (``found=True``):
          no ``<identifier>.rst`` but ``<identifier>.<child>.rst`` siblings exist.
          Extra key: ``submodules`` (list of child identifiers).
        - ``"definition"`` (``found=True``):
          *identifier* is defined inside a parent RST
          (e.g. ``bpy.props.IntProperty`` lives in ``bpy.props.rst``).
          Extra keys: ``content`` (rendered block), ``examples``.
        - ``"partial"`` (``found=False``):
          the parent RST was located but the trailing component isn't defined in it.
          Extra keys:
          - ``parent`` the identifier whose RST was loaded.
          - ``available`` top-level definitions in that RST.
          - ``submodules`` sibling identifiers ``<parent>.<child>`` with their own RSTs,
            filtered to those whose last component contains every character of the missing tail.

          For a toctree landing page like ``bpy.types`` ``available`` is empty and ``submodules``
          is the near-miss list; for a self-contained module like ``bpy.props`` it's the reverse.
        - ``"suggestions"`` (``found=False``):
          no direct match, but *identifier* appears as a component of other files.
          Extra key: ``suggestions`` (list of full identifiers).
        - ``"missing"`` (``found=False``): nothing matched.

        ``examples`` (present on the ``exact`` and ``definition`` kinds)
        is a list of ``{path, content}`` entries referenced from this documentation.

[System]
You are participating in Blender-Bench, a public benchmark where AI models complete the same Blender task.

Your result will be compared head-to-head with another model. Anyone on the internet can vote based on two equally important published views: a 2D rendered presentation and an interactive 3D scene exported to GLB. Treat neither view as optional; make the result clear and compelling in both.

Complete the request as well as you can. The benchmark does not prescribe a workflow or visual style; use whichever Blender techniques you consider appropriate. Make the important requirements evident in the published result, save a complete scene, and present the work clearly in every requested output.

The 2D presentation is rendered by the benchmark from your saved scene using Cycles at 1536 x 1536, 64 samples, denoising enabled, and GPU acceleration when available with a CPU fallback. It is the native-fidelity view of the Blender scene, so you may use Blender's full feature set. Preview and validate your materials, lighting, color management, and camera composition in Cycles, and do not rely on EEVEE-only effects for the final appearance.

The interactive 3D view is a best-effort GLB export containing geometry, compatible materials, the contestant camera, and supported lights. Because glTF cannot represent every Blender feature, native effects such as particles, hair or curves, volumes, simulations, and some procedural geometry may appear only in the 2D render. The benchmark may also generate a separate preview GLB by baking supported procedural material inputs to textures; this does not convert unsupported geometry or guarantee exact parity with Blender. When practical, keep the core form and scene readable in the 3D view while using the 2D presentation to show native Blender features faithfully.

## Harness Instructions

You are operating Blender through the provided tools. Tool calls execute one at a time, in the order you issue them, against a single live Blender instance — each call sees the state left by the previous one, and issuing several calls in one message gains no parallelism. The scene starts empty. Build what the user's prompt asks for in the current scene. Work step by step and verify your own work.

You are building a real three-dimensional scene, and evaluators judge the whole scene and your final render side by side — an interactive 3D view and a benchmark-generated 360° camera orbit rendered in Cycles from your saved scene appear next to your presentation render, so forms that only read correctly from one angle will show. Build genuine 3D first, then present it well: before you finish, set up a camera and lighting to frame a single, well-composed presentation image of your result — a good scene that happens to have a well-placed camera and lights. The final benchmark capture overrides the scene render settings and renders in Cycles at 1536x1536, 64 samples, with denoising and GPU acceleration (CPU fallback). Preview and validate materials, lighting, color management, and composition in Cycles; do not rely on EEVEE-only effects. Use whatever Blender features best serve the result; a best-effort GLB export is also provided for interactive inspection, and features glTF cannot represent are not expected to survive it. When you are finished, reply with the single word DONE and no tool calls.

[Assistant] The screenshot tool returns no image data, so I'll verify visually via a rendered PNG and inspect it numerically. Let me first analyze the rendered image with Python to check composition and brightness.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "exists True size 2289161\ndims 1536 1536 mean RGB [0.416 0.445 0.28 ]\nmin/max 0.007843137718737125 0.6823529601097107\ncenter [0.125 0.204 0.055]\ntop band mean [0.535 0.555 0.364]\nbottom band mean [0.412 0.406 0.29 ]\n"
}

[Assistant] The render is fairly bright overall. To see the actual image, let me save a small version and check with the screenshot API, or better — verify the scene structure and check for common issues (e.g., geometry clipping, materials). First, let me confirm which objects are visible and check the cabin alignment.

  "status": "ok",
  "result": {},
  "stdout": "counts {'MESH': 256, 'LIGHT': 3, 'CAMERA': 1}\nCabinFloor loc <Vector (-4.0000, 1.0000, 0.4700)> dim <Vector (4.2000, 3.2000, 0.1750)>\nRoof loc <Vector (0.0000, 0.0000, 0.0000)> dim <Vector (10.2000, 7.8000, 2.5600)>\nChimney loc <Vector (-4.5000, -0.6000, 3.6000)> dim <Vector (0.5500, 0.6000, 3.2000)>\nPondWater loc <Vector (0.0000, 0.0000, 0.0000)> dim <Vector (14.0000, 14.0000, 0.0000)>\nDoor loc <Vector (0.0800, 2.2000, 1.6700)> dim <Vector (0.0600, 0.8500, 1.2500)>\nAwning loc <Vector (0.6000, 2.2000, 3.0500)> dim <Vector (0.5000, 1.6600, 0.0600)>\npond dims <Vector (14.0000, 14.0000, 0.0000)>\ncam dir <Vector (-0.7189, 0.6942, -0.0349)>\ncam loc <Vector (11.0000, 7.5000, 1.7500)>\n"
}

[Assistant] The camera is looking roughly at the cabin area. Let me actually view the rendered output by copying it into the Blender image editor and reading it via the screenshot, or better — I'll analyze the render more carefully for problems. The render shows greenish center (0.125, 0.204, 0.055 — likely foliage/grass), so the cabin may be visible but let me check the actual frame by examining a downscaled ASCII visualization of the luminance.

}

[Assistant] The ASCII map is hard to interpret. Let me open the render in an Image Editor and screenshot that area to actually see it.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "switched area\nimage CheckRender <bpy_int[2], Image.size>\n"
}

[Assistant] The screenshot tool returns no data (likely not supported in this environment). I'll rely on numeric analysis plus targeted render-region checks. Let me check where the cabin lands in the frame and whether the pond/cabin are framed well.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cabin_front_center -> (-2.062, 0.009)\ncabin_ridge -> (-2.116, 0.654)\ncabin_left -> (-1.677, 0.053)\ncabin_right -> (-3.117, 0.093)\npond_center -> None\npond_far -> None\npond_near -> None\ndock_start -> None\ndock_end -> None\ndoor -> (-2.319, -0.0)\nchimney -> (-2.631, 0.546)\ntree_back_l -> (-0.991, 0.18)\ntree_back_r -> (-0.819, 0.35)\n"
}

[Assistant] The cabin is at NDC x≈-2 to -3, which is far off-screen to the left (visible range -1..1). My projection math might be off due to focal length handling, but the camera clearly isn't framing the scene well — pond points returned None (behind camera or outside). Let me reposition the camera to properly frame the cabin, pond, and dock from a good angle.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cam loc <Vector (13.5000, 6.5000, 2.6000)> rot <Euler (x=1.5708, y=-0.0000, z=1.9720), order='XYZ'>\ncabin_front_center -> (-2.062, 0.009)\ncabin_ridge -> (-2.116, 0.654)\ncabin_left -> (-1.677, 0.053)\ncabin_right -> (-3.117, 0.093)\npond_center -> None\npond_far -> None\npond_near -> None\ndock_start -> None\ndock_end -> None\ndoor -> (-2.319, -0.0)\nchimney -> (-2.631, 0.546)\ntree_back_l -> (-0.991, 0.18)\ntree_back_r -> (-0.819, 0.35)\n"
}

[Assistant] My manual projection is suspect. Let me use Blender's own `world_to_camera_view` to check framing.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cabin_front_center -> (0.613, 0.436)\ncabin_ridge -> (0.613, 0.73)\ncabin_left_corner -> (0.529, 0.47)\ncabin_right_corner -> (0.759, 0.448)\npond_center -> (-0.66, 0.207)\npond_far -> (-0.97, 0.264)\npond_near -> (-0.153, 0.113)\ndock_start -> (-0.148, 0.325)\ndock_end -> (-1.618, 0.253)\ndoor -> (0.609, 0.417)\nchimney -> (0.53, 0.645)\ntree_back_l -> (0.952, 0.579)\ntree_back_r -> (1.14, 0.67)\n"
}

[Assistant] The cabin is on the right side (x≈0.6), pond on the left, but the dock extends off-screen left, and the cabin is too far right. Let me adjust the camera to get a balanced composition: cabin centered-ish, pond + dock visible in foreground, trees framing.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cabin_front_center -> (0.621, 0.432)\ncabin_ridge -> (0.621, 0.746)\ncabin_left_corner -> (0.531, 0.468)\ncabin_right_corner -> (0.777, 0.444)\npond_center -> (-0.743, 0.186)\npond_far -> (-1.075, 0.247)\npond_near -> (-0.2, 0.085)\ndock_start -> (-0.194, 0.312)\ndock_end -> (-1.769, 0.235)\ndoor -> (0.616, 0.411)\nchimney -> (0.532, 0.655)\ntree_back_l -> (0.984, 0.585)\ntree_back_r -> (1.186, 0.682)\n"
}

[Assistant] Still off. The dock is off-screen left and the cabin pushed right. I need to move the camera further away/back so both fit. Let me try a wider, more frontal composition.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cabin_front_center -> (0.631, 0.415)\ncabin_ridge -> (0.63, 0.807)\ncabin_left_corner -> (0.577, 0.454)\ncabin_right_corner -> (0.734, 0.442)\npond_center -> (-1.056, 0.174)\npond_far -> (-1.207, 0.247)\npond_near -> (-0.756, 0.028)\ndock_start -> (-0.422, 0.295)\ndock_end -> (-1.948, 0.261)\ndoor -> (0.543, 0.398)\nchimney -> (0.536, 0.688)\ntree_back_l -> (1.137, 0.609)\ntree_back_r -> (1.181, 0.815)\n---\ncabin_front_center -> (0.618, 0.424)\ncabin_ridge -> (0.617, 0.776)\ncabin_left_corner -> (0.569, 0.458)\ncabin_right_corner -> (0.71, 0.448)\npond_center -> (-0.901, 0.206)\npond_far -> (-1.036, 0.272)\npond_near -> (-0.631, 0.075)\ndock_start -> (-0.33, 0.316)\ndock_end -> (-1.703, 0.285)\ndoor -> (0.539, 0.409)\nchimney -> (0.532, 0.669)\ntree_back_l -> (1.073, 0.598)\ntree_back_r -> (1.113, 0.784)\n"
}

[Assistant]
The issue is clear now: the dock runs off to the left far out of frame, and the pond center is far left too. The cabin occupies only the right portion. I need to rethink the composition: move the camera to the east, looking west, so the cabin is left/center and the pond extends right, or better, reposition the dock so it points toward the camera.

The dock currently extends from shore (4.6,-4.9) toward (11.6,-12) — away from the camera position. The camera at (10-16, 8-11) is north of the dock. The dock should point toward the viewer. Let me rotate the dock to point southeast toward the camera-side shore, and place the camera south of the pond looking north at the cabin.

Let me reconsider the whole layout: cabin at (-4,1), pond centered (8,-7). The pond's near shore to the camera should be its south side (y=-13). If the camera is at (6, -16) looking north, the cabin would be behind the pond. Better: camera east of pond at (15, -2) looking west-northwest toward cabin (-4,1). The dock from shore toward the pond center — from (4.6,-4.9) toward (8,-7) — that's toward the pond center, which is toward the west from the camera. That would point mostly away.

Actually, for a classic composition: cabin on the left/center, pond in front stretching to the right, dock reaching from the shore toward the viewer/camera. Camera positioned south-east of the pond, e.g., (10,-10), looking northwest at cabin (-4,1). Then the pond is in the middle foreground, the dock from (4.6,-4.9) extending southwest toward the camera would be visible.

The dock direction (0.70,-0.71) normalized points from shore (4.6,-4.9) to (11.6,-12.0). That's pointing southeast. A camera at (10,-10) is roughly southeast of the shore — so the dock would point somewhat toward the camera.

Let me set the camera at (11, -9, 2.5), target (-3, 1, 2.5). Check the projection.The dock is pointing away from my camera. Let me place the camera south of the pond looking northwest, so the dock points toward the viewer and the pond fills the foreground.

[Tool]

  "stdout": "cabin_front_center -> (0.634, 0.471)\ncabin_ridge -> (0.636, 0.737)\ncabin_left_corner -> (0.592, 0.516)\ncabin_right_corner -> (0.7, 0.457)\npond_center -> (-0.328, 0.298)\npond_far -> (-0.529, 0.353)\npond_near -> (-0.024, 0.215)\ndock_start -> (-0.004, 0.376)\ndock_end -> (-0.83, 0.345)\ndoor -> (0.583, 0.438)\nchimney -> (0.569, 0.664)\ntree_back_l -> (0.983, 0.609)\ntree_back_r -> (0.925, 0.6)\n"
}

[Assistant]
Better — pond is now left-center, dock visible from (0, 0.38) to (-0.83, 0.35). But the cabin is still far right (x≈0.63) and the dock end at x=-0.83 is near the left edge. I want the cabin more central and the dock clearly in the foreground. The cabin is at x≈0.63, pond center at -0.33 — the whole scene spans -0.85 to 0.98.

Let me pull the camera back and shift the aim left/down so the cabin sits around x=0.55 and the dock sweeps from center toward the lower-left, with pond filling the bottom.

[Tool]
{
  "status": "ok",
  "result": {},
  "stdout": "cabin_front_center -> (0.499, 0.451)\ncabin_ridge -> (0.499, 0.756)\ncabin_left_corner -> (0.234, 0.485)\ncabin_right_corner -> (0.834, 0.467)\npond_center -> (0.047, -0.34)\npond_far -> (-5.71, -2.167)\npond_near -> (1.181, 0.02)\ndock_start -> (0.307, 0.188)\ndock_end -> (5.196, 3.22)\ndoor -> (0.726, 0.431)\nchimney -> (0.388, 0.677)\ntree_back_l -> (0.606, 0.596)\ntree_back_r -> (1.192, 0.619)\n"
}

[Assistant]
Now the cabin spans x 0.23–0.83 (center ~0.53), pond center at (0.05,-0.34), dock start (0.31,0.19) but dock end goes off to (5.2,3.2) — that means the dock extends toward the upper right, away from the camera (because from this angle, the dock direction points away). The pond near shore at y=0.02 is at the bottom.

Wait — the dock end at (5.2, 3.2) is far off-screen. That means the dock points away from the camera toward the pond's far side. That's wrong for the composition. The dock should point from the shore INTO the pond — which is what it does geometrically — but from the camera's viewpoint, the pond's far side is behind/right.

Actually looking at the layout: the pond is at (8,-7), the dock goes from (4.6,-4.9) toward (11.6,-12). The camera is at (14.5,-6). The dock is to the left of the camera. From the camera, the dock's far end (11.6,-12) is further left AND further away (more negative y, farther from camera at y=-6). So it should project toward the left... but it shows x=5.2? That suggests my projection is inconsistent — the dock end is beyond the pond far edge.

Let me stop guessing and reconsider: The real problem is the dock is oriented the wrong way for a camera on the south side. I should rotate the dock to point from the shore toward the pond's near side (south), i.e., from (4.6,-4.9) toward (4.6,-10) — toward the camera at (14.5,-6) roughly. Then from the camera, the dock would lead from the shore toward the viewer, appearing in the foreground.

Let me rotate the dock direction to point toward the camera-side (south-southwest). The pond edge nearest the camera is around (8,-13). The shore near the dock start is (4.6,-4.9). A dock from (4.6,-4.9) toward (5.5,-9) would point south, into the pond, toward the camera.

Actually the dock should extend from the shore INTO the pond. The pond center is at (8,-7). The dock at (4.6,-4.9) extending toward (8,-7) would reach the pond center — but that's mostly east. From camera (14.5,-6) looking at cabin (-3.5,1), the pond center (8,-7) projects near center-bottom. A dock pointing from (4.6,-4.9) toward (8,-7) — its far end would be near the pond center, which is in the lower middle of the frame. That would look great: the dock juts into the pond toward the camera.

The current dock goes toward (11.6,-12) which is beyond the pond's far south-west edge — wrong, it goes past the pond. I should rebuild the dock to point from the shore toward the pond center.

Let me rebuild the dock with direction from (4.6,-4.9) toward pond center (8,-7), length ~7, so it ends around (7,-6.4).

[Assistant]
Now the dock end at (-1.48,-0.89) is off-screen bottom-left, meaning the dock still extends too far left. The dock start is at (0.18,0.21) but it runs past the pond's near edge. The dock is 7.5 long pointing toward pond center; the pond center is at (0.18,-0.17)... wait no, the pond center projects to (-0.18,-0.17), and the dock end (-1.48,-0.89) is beyond the pond center — because the dock extends past the pond center toward the far edge.

The dock from (4.6,-4.9) toward (8,-7) at length 7.5 ends at (10.98,-8.84) — that's beyond the pond center (8,-7), near the pond's far edge (13,-12). The dock is too long and crosses the whole pond. I should shorten it to ~4.5 so it ends around (7.2,-6.3), just inside the pond near the shore, giving a nice jutting dock.

}

[Assistant] Now the dock spans from (0.18, 0.21) to (-0.29, -0.10) — nicely in the lower-center-left of the frame, leading into the pond. Cabin at (0.49, 0.45) with ridge at 0.74. Let me now render a test and analyze the composition.

}

[Assistant] The cabin is visible (warm wood tones at center), but the pond center and dock mid are off-screen — the pond is mostly below the frame. The current camera is too low/close, and the dock is at the bottom edge. I need a higher, more pulled-back camera to capture the pond fully with the dock visible. Let me adjust.

}

[Assistant]
Still the pond center is below frame (y<0). The pond's near shore is at (0.86, 0.08) — right at the bottom edge. The problem: the pond sits mostly below the camera's view because the camera is positioned too far north (y=-4) and the pond center is at (8,-7), far south. The camera at y=-4 looking toward (-2,-1) means the pond is behind/below.

Let me reposition the camera to be south-east of the pond, looking north-west. That way the pond is in front (between camera and cabin).

Still the pond center is below the frame (y=-0.104). The issue: the pond is at y=-7 but the cabin at y=1 is BEHIND the pond from this camera. The pond is between the camera and cabin, so it should fill the lower part of the frame... but the numbers show pond_center at y=-0.104 (below frame bottom) — meaning the pond is still below the view. That's because the camera is aiming too high (at y=1 cabin), and the pond at y=-7 is far below the aim point.

The geometry: camera at (9,-16.5), aiming at (-3.5,1). The line of sight passes over the pond. The pond center (8,-7) is laterally offset from the aim line. It should appear lower in frame but not off-screen.

The projection says pond_center y=-0.104 — just barely below the bottom edge. I need to tilt the camera down slightly or move it further away. Let me aim lower, at the pond/cabin midpoint, and move camera back.
