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.

LightWave → Modern Web

WebConverter reads LightWave .lwo through Assimp and writes a modern glTF 2.0 or GLB via Magnum.
