Missing UVs when exporting GLB file.

[idealight]

Have an issue with some geometry export. During a light bake all UVs seams to be ok, but after an export some parts\meshes are dissapear in the UV (2nd channel). I have already tried everything (Reset Xform, Weighted normals, Reset Scale)

I notice that GLB missed somethimes some parts of UVs. But FBX exports UVs properlly.

Please see the pictures

Also note that I do not why but therer is also mismatch in Vertexes quantity 14 221 vs 34 970

     

What did I miss and what should i try to reset to fix this issue?

Any suggestions?

Thank you!

how do you control the uv set and vertex count after export? how do you import GLB file back?

what MAX version do you use?

Thanks for your answer 2024 Max - and Blender

About differences in vertices its the problem that exporting or importing GLB breaks the geometry not by element how it was but randomly by poligons sometimes.

I import GLB to Blender. No possibility to check it on MAX

that's why I ask...

why do you think MAX is doing something wrong and not Blender?

by the way... you can try to export JSON (text, not a binary) version. At least you will be able to control why Blender can't import it.
