The GLTF mesh is loaded and re-exported as GLB. Straight geometry conversions go through trimesh; when textures and materials need to survive the trip, the job is handed to Blender instead.
Settings this conversion runs with
| Loader | trimesh |
|---|---|
| Textured path | Blender (GLB, glTF, OBJ) |
| Materials | Preserved |
What changes
- GLB packs the mesh, materials, and textures into a single binary file, which is what makes it the practical choice for the web and AR viewers.
