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

Why GLB?
.glb is the binary container for glTF 2.0: a single self-contained file that bundles geometry, materials and embedded buffers. WebConverter reads your FBX with ufbx, then writes the GLB via Magnum's GltfSceneConverter. Optionally re-encode meshes for the GPU vertex cache and simplify them with meshoptimizer.
