Create a new public demo only in blender-lantern/ within this project, preserving every existing file elsewhere. Make an original polished miniature rooftop conservatory diorama in Blender 4.5: warm glowing lanterns, cream stone base, sage greenhouse frame, broad-leaf plants in terracotta planters, stepping stones, curved bench, lavender twilight backdrop, orthographic camera. No external assets, network, downloads, credits or paid services. Write build_scene.py with the Blender Python API, README.md and then run the installed Blender executable at C:/Program Files/Blender Foundation/Blender 4.5/blender.exe in background to generate lantern.blend and render.png (960x640, EEVEE, low render samples, one still only). The script must resolve outputs relative to itself; do not delete files outside this new demo directory. Record actual Blender version, commands and checks in README; do not claim visual QA unless performed. No browsers. If execution needs permission, ask; never change security settings. Stop after the files and render are ready.

Follow-up requests

The generated Blender render is valid, but operator visual QA found the greenhouse roof cropped by the top edge. Change only blender-lantern/build_scene.py camera framing: zoom the orthographic camera out enough to keep the complete roof, base and all sides inside the image with about 10% breathing room. Preserve the scene design. Re-run the same Blender command to update lantern.blend and render.png, record this follow-up in README, and stop. No additional downloads, browsers or online media.

Checks and limits

• Agent execution record: Blender 4.5.10 LTS, EEVEE, 32 samples, 960×640 PNG and .blend scene saved.
• Operator visual review: the initial roof was cropped; after one Agent follow-up the complete roof and base fit inside the frame. The requested 10% margin is approximate, not a measured acceptance criterion.
• Operator integrity checks: all published files retain their original bytes and SHA-256.

No universal speed or reliability claim is made.

• One still-image scene, not an animation, interactive game or production asset pipeline.
• The initial framing required a follow-up; this is not a universal first-attempt success claim.
• Agent reported two RNA property warnings; rendering still completed.
• Uses an online free language model to author the scene; local Blender rendering is not proof of local AI inference.
• No Unity, Unreal or Godot project is validated by this case.

Human and operator interventions

• Codex supplied the prompt and operated Donatello Agent.
• Agent wrote the scene script and ran installed Blender; the operator requested one framing correction.
• Codex inspected and exported the resulting files; the generated scene code was not rewritten by the operator.
• The isolated image viewer is an operator-created presentation wrapper, not another Agent-generated project.

Download and verify the actual files

Generated source is preserved unchanged. Operator-created test records and presentation wrappers are identified above. Compare each file's SHA-256 with this record.
