USD import issue when trying to import skeleton with animation

Hello. I’m having an issue when I try to import an animated skeletal through the USD Stage Editor. The skeletal mesh gets imported without issue if it has no animation, but it has an animation then the mesh is imported with texture issues, seemingly without its UV map applied, but with the animation working. Any texture added to this broken mesh just becomes one solid color.

Here is what the skeletal mesh looks like when imported without animation. Everything correct:

And here is how it looks like when it’s imported with an animation, no texture changing the material just results in solid colors:

Here are the export settings for the USD in Blender, if I uncheck the “Animation” box then everything works fine but obviously it doesn’t send the animation data:

Does anyone know what could be causing this? Thanks.

Would you be able to share the two files (with/without) animation?

For sure, here they are. Thanks!

usd anim.rar (6.0 KB)

I could reproduce. The UV is missing on the skeletal mesh on the model with the animation.

The cube looks good in USDView and in UE if I import with Interchange OpenUSD. Thus, it looks like something wrong in the USD Stage Editor. I created a bug (it can take some time for the link to become active) for dev to review.

Thank you very much!
