This package turns LDraw assemblies into Blender scenes for rendering using materials and scene setup adapted from Eyesight.

Install

pip install bricknet-render bricknet "bpy>=5.1"

Python 3.13+ and Blender/bpy 5.1+ are required. If using standalone Blender, do not install bpy separately.

python -m bricknet_render fetch-glbs

Part meshes use BrickNet's user-data directory; set BRICKNET_DATA to move it.

Rendering

bricknet-render model.ldr out/one
bricknet-render model.ldr out/views --views 8
bricknet-render model.ldr out/hdr --env-map room.exr

Add --save-blend scene.blend to retain the Blender scene.

Scripts

python scripts/render_falling.py scripts/data/car.ldr out/falling
python scripts/color_by_path.py scripts/data/car.ldr out/path
python scripts/render_material_catalog.py out/materials
