Procedural Generation by Automating Blender
summary
Generates rock/asteroid assets by scripting Blender’s UI with the Blender Python API, using metaballs to form base shapes, bmesh to convert to meshes, then applying a subsurf and displace modifier for detail, decimating to a low‑poly target (example runs drop ~22k tris down to ~1,254 tris), smart UV unwrap, bake normal and diffuse maps, export FBX and import into Unity; all steps are automated from the operator log, saved to disk, and produce ready‑to‑use assets.
