Short description of error
[Please fill out a short description of the error here]
Hello, I'm Japanese.
I am not good at English and use the translation function.
I'm sorry if it's hard to understand.
I want to export an animation with two blend shapes in Maya in glb, but it doesn't work.
I get the following error:
Traceback (most recent call last):
AssertionError
location: :-1
Is it possible to put an FBX with a blend shape in a blender and export it to glb or gltf?
Thank you.
Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]
Import FBX from Maya to blender (2 blend shapes) → Mesh breaks.
Some models could be imported with Alembic.
Blend shapes are applied in Maya and Unity, so I think that FBX contains the blend shape data. (Maybe...)

I think it should, but could you share the .fbx file that fails to import into blender?
Thank you for answering!
I'm sorry, but I can't share it because it's Company work data.
However, I gave up on Blend Shape and finished this work safely.
Can you tell me the possible causes for your reference?

I'm having the same issue trying to import a character that I previously exported with Blender. I'm working in UE4 and tried exporting my same character back getting the same errors as above. Here is the FBX...
