Room Creator

Generate room scenes with room-cli -m embodied_gen.scripts.room_gen.gen_room from infinigen(https://github.com/princeton-vl/infinigen) and optionally export URDF/USD. room-cli forwards its arguments to the bundled Blender Python (has bpy and room deps installed by bash install.sh room); running python -m embodied_gen.scripts.room_gen.gen_room from the embodiedgen env works too since heavy stages dispatch to Blender Python internally either way.

Use This Workflow

1. Confirm output root and target room profile.
2. Choose generation scope:

• --gen --urdf --usd for full pipeline.
• --gen --no-urdf --no-usd for generation only.
• --no-gen --urdf --usd for export from existing blender output.

1. Run the command from repository root.
2. Verify output folder: <output_root>/<RoomType>_seed<seed>/ (if --seed is omitted, check the generated seed from logs first).

Parameters

• --output-root (required): base output directory.
• --prompt: natural-language task/scene description; a GPT router infers room type and complexity from it, overriding --room-type/--complexity. Requires a configured GPT agent.
• --room-type: Bedroom | LivingRoom | Kitchen | Bathroom | DiningRoom | Office | House.
• --seed: random seed. For reproducible runs, pass this explicitly; if omitted, a random seed is generated.
• --complexity: minimalist | simple | medium | detail.
• --custom-params: gin file copied to Infinigen custom_solve.gin.
• --large-scene: only for House; enables more rooms.
• --gen/--no-gen, --urdf/--no-urdf, --usd/--no-usd: pipeline switches.

Complexity Guidance

• minimalist: fastest, sparse furniture.
• simple: default, balanced quality/time.
• medium: richer layout, slower.
• detail: highest detail, longest runtime.

Command Templates

# Full pipeline for one kitchen
room-cli -m embodied_gen.scripts.room_gen.gen_room \
  --output-root outputs/rooms \

  --output-root outputs/rooms \
  --room-type House \
  --seed 7 \
  --complexity simple \
  --large-scene

Runtime Requirements

• Run from repo root so relative paths resolve.
• room-cli resolves Blender Python from $BLENDER_PYTHON_BIN if set, else falls back to

thirdparty/infinigen/blender/4.2/python/bin/python3.11 (must exist on disk).

• --no-gen requires existing blender output at:

<output_root>/<RoomType>_seed<seed>/blender.
