System Information
Operating system: Mac OS 14.3
Graphics card: Apple M3 Pro

It also happens with every Windows 10/11 machine I tested.

Blender Version
Broken: 4.0.2

Short description of error
When exporting the attached .blend file as GLTF, Blender hangs indefinitely.
If I first triangulate the faces of the mesh, then it is exported immediately and successfully.

Exact steps for others to reproduce the error
File > Export > glTF 2.0 > Export glTF 2.0

Hi @pmh.pereira,

Thank you for reporting this issue. However, it seems that the mesh in the attached .blend file is invalid, which is causing Blender to hang when exporting as GLTF.

Without clear instructions on how to recreate this invalid mesh from scratch, it is difficult for us to debug this further. Mesh corruption can occur due to various factors such as importers, development versions of Blender, or modeling tools.

Attached the mesh "fixed"

Hi @mano-wii,

This asset was made by a client of ours so I'm not sure how they made it. I'm gonna guess Maya.
They have a lot of other assets (also made by them) and all of them export successfully to GLTF.

What exactly made this mesh "invalid"? So we can check for that in the future.

Thanks.

What exactly made this mesh "invalid"?

I attached a log that shows the errors that were detected in the mesh.
In short, it looks like it has some duplicated faces (sharing the same vertices) and some unused loops.

No activity for more than a week, so closing.
If you find more information on how to make this corrupted mesh, please open a new report.
