Error when converting to GLTF, GLB, USDZ

General Issues & Bug Reporting (Fab)

Summary

Hi, at this point I had no problem with converting Static 3D models, but for my last asset I had an error converting to GLTF, GLB, USDZ
For information : The main difference between the others who did well converted is that the 3D who did the error is a skeletal mesh with an animation and 2 uvmap.

What type of bug are you experiencing?

Steps to Reproduce

What I did (multiple times) :

  1. Went to the GLTF, GLB, USDZ section
  2. Selected the FBX source file
  3. Confirmed the selection
  4. Edited the 3D setting (adjust the materials)
    At this point my 3D is well previewed (animation, material,…)
  5. When I clicked « Convert Files » it began the conversion
  6. And : “An error occured”

Expected Result

Fab convert 3D to GLTF, GLB and USDZ

Observed Result

“An error occured” message

Platform

Chrome 129 (arm64)

Operating System

macOS Sequoia 15.0

Additional Notes

I don’t think the problem comes from the source .fbx because it is well previewed by the fab 3D viewer. Thanks for your support

Thanks, but I think it would be better if the conversion could be done directly by the fab system; may be the converted files will be linked, referenced or shared; then I don’t want to override the Fab system.
