modelImport

The model-import pipeline. Decomposes any assimp-supported 3D model (.fbx, .obj, .dae, .gltf, .glb, .stl, .ply, .3ds, and more) into meshes, materials, textures, animation clips and a node graph; extracts a single clip to its .zanim payload; and derives a .rig from a skinned mesh or from an animation-only file's driven skeleton.

The public Luau surface over the __model (model decompose + clip extraction) and __rig (skeleton derivation) Internal FFI namespaces. decompose(bytes, ext) forwards the real source extension to assimp as the format hint, and every format decomposes into the same shape. Importers and any content that brings model files in go through this surface.
