FBX is loaded via ufbx, other formats via Assimp
Supported: FBX, OBJ, DAE, PLY, STL, GLTF, GLB, 3DS, LWO, BLEND, X
Output format
.glb is a single compact binary file; .gltf is JSON with embedded buffers (easier to inspect).
Optimize meshes for the GPU
Re-orders vertices and triangles for vertex-cache locality, overdraw and vertex fetch. Produces smaller, faster files.
Simplify meshes
Reduce triangle count by the chosen percentage. 0% keeps every triangle.
Compress textures to KTX2 (Basis Universal)Soon
Re-encode embedded textures as supercompressed KTX2 for tiny GPU uploads. Wiring is in place; the encoder module ships in a follow-up.
