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>

YGG-1, a compact deep-space survey spaceship built to listen and observe rather than fight. Its defining silhouette is a dense central body embraced from behind by exactly three thick, rear-swept engine wings: one dorsal wing and two mirrored lateral wings. The craft must read unmistakably as a machine for vacuum, never as a boat, submarine, or conventional airplane.

Central body. Use a short, thick fuselage rather than a long needle-shaped hull. A narrow nose and small forward cockpit grow deeper and wider toward the middle and rear, concentrating the greatest mass around the wing couplings and power systems. The profile should feel compact and slightly wedge-shaped: fine at the cockpit, muscular through the core, and tightly resolved at the aft section. Mark the hull clearly with the serial designation YGG-1 in a restrained technical typeface.

Cockpit. The cabin is deliberately small relative to the ship. Use a low faceted canopy tightly integrated into the forward hull, with genuinely transparent but darkened glazing. Reveal only a compact seat silhouette and a restrained warm-amber console glow. Avoid a large bubble canopy or passenger-aircraft proportions.

Rear-mounted bent wings. Mount all three wings around the rear third of the central body, leaving the cockpit and forward fuselage unobstructed. Each wing is a broad two-segment form resembling a mirrored L with a smooth engineered elbow. A short, thick base floats beside the rear fuselage; from that base the wing extends outward briefly, bends through an internal angle of roughly 120–135 degrees, and then sweeps strongly backward. The two lateral wings mirror each other, while the dorsal wing follows the same bent geometry in the vertical plane instead of standing straight up like a tail.

The long rearward segments must extend farther away from the body than the short bases, with generous clearance and widely separated tips. Their pointed ends sit well behind the roots and away from the fuselage, creating three long swept hooks around the rear of the ship. Avoid straight radial wings, forward-pointing tips, thin airplane fins, or a compact cluster of tips close to the hull.

Maglev attachment. Only each wing’s short base is held by the magnetic-levitation system. A clearly visible empty gap separates every base from a recessed hull emitter cradle. Matching armored receiver plates, restrained cyan-violet field light, and fine magnetic filaments span the gap; no physical strut, hinge, cable, or material connection may cross it. The maglev coupling must connect to the base, never the middle of the long wing segment.

Engines inside the wings. The wings are thick, volumetric propulsion modules rather than decorative fins. Embed each main engine inside the broad inner portion near the base and elbow, with a dark recessed propulsion channel continuing into the rearward segment. Contained white-blue energy should glow from deep inside this structure, not from oversized external flames. Keep the brighter engine light visually distinct from the softer cyan-violet maglev field. Inset radiator surfaces and thermal channels may support the design, but the outer skin should remain sleek.

Survey equipment. Integrate a small number of flush sensor apertures and narrow instrument windows into the central hull. Remove external antenna masts, whip antennas, turrets, and other protruding equipment so the silhouette stays clean. Nothing may resemble a cannon, missile rack, or weapon mount.

Surface design. Use pearl-white ceramic composite over a dark gunmetal internal structure, with satin finishes, smooth computed curvature, and darker heat-resistant material around engines and maglev emitters. Keep panel divisions sparse and purposeful: a few large service boundaries and access hatches rather than dense paneling or decorative greebles. Add subtle anodized accents and faint iridescence where the field light washes the wing bases. The ship is maintained and flight-ready, with no rust, grime, patched plating, or heavy weathering.

Presentation. Show YGG-1 from a frontal three-quarter angle with enough side visibility to make the bent wing geometry unmistakable. The small cockpit and thick central mass should project forward between the three rear-swept hooks; all three maglev gaps, wing elbows, internal engine channels, and widely separated rearward tips must be visible. Use a dark starfield and restrained rim lighting so the amber cockpit, white-blue engine cores, and violet-cyan suspension fields remain legible.
