3D model to transparent image

arka model_to_image chair.obj --output chair-render.png
arka model_to_image asset.glb --output public/assets/asset.png --size 2048
arka model_to_image asset.glb --output hero.png --task "product hero image"
arka model_to_image asset.glb --output roof.png --angle top

Arka uses Blender for cross-platform mesh rendering, produces a transparent PNG, then runs the existing background-removal skill to remove residual pixels. Supported mesh inputs are OBJ, STL, GLB, and GLTF. Install Blender on PATH and the vision extra for background removal. Use --keep-background when a rendered transparent canvas is preferred without rembg processing. The camera defaults are semantic, not random. Pass --angle front|front-three-quarter|rear|rear-three-quarter|side|three-quarter|top|underside when the composition is known. With a VLLM server configured (VLLM_API_URL and optionally VLLM_MODEL), --task lets the local model choose the most useful view for that task. If VLLM is unavailable, Arka falls back to deterministic symbolic rules: “roof” selects top, “side profile” selects side, and racing game vehicle tasks select rear-three-quarter so the car is viewed from behind like a normal third-person racing game.
