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 only on the published visual outputs they can inspect: the interactive 3D scene and rendered presentation. 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 final published capture 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. The saved scene is also exported to GLB with geometry, materials, the contestant camera, and supported lights for interactive inspection. 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. ## Harness Instructions You are operating Blender through the provided tools. 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. Before you finish, set up a camera and lighting to frame a single, well-composed presentation image of your result — position and aim the camera, and add or adjust lights so the subject reads clearly. 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. The saved scene is also exported to GLB with geometry, materials, your camera, and supported lights for interactive inspection. When you are finished, reply with the single word DONE and no tool calls.
--TASK camp-lantern: ## Task
Complete the following Blender task:
<task>
A classic camping lantern as a single hero prop: a metal frame with a carry handle, a
glass enclosure around a warm glowing core, standing on simple ground.
The floor is a recognizable lantern that glows. The ceiling is what the light does:
warm light passing through the glass, a soft pool of illumination on the ground,
believable metal and g…

## Scene Summary
I created a **classic camping lantern** as a single hero prop in Blender, composed of 37 objects across 6 materials:
### Lantern Geometry:
- **Base plate** - Circular metal disc with beveled edges
- **Base collar** - Raised ring on top of the base
- **Cage frame** - 4 vertical metal bars forming a protective cag…
