- When you need it for modeling
- To open your files in apps that prefer 3MF
- To share 3MF files more easily
What happens to your file
The GLB mesh is loaded and re-exported as 3MF. 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 | Not supported by the target |
What changes
- 3MF describes geometry, not appearance. Textures, materials, and UV maps in the GLB are not written into the output — if the model is textured, keep the original alongside it.
