I'm puzzled because I'm seeing this for the first time. I was rendering an asset with XPU and I noticed that some parts have UVs rotated 90 degrees. These areas are rendered correctly on Karma CPU, as well as OpenGL.
There's nothing unusual about the asset. Just a mid-poly object with UVs and MaterialX with some textures. No fancy configuration.
I will continue debugging the scene, as it's possible that I made a mistake somewhere. But meanwhile, I thought I'd ask if perhaps someone already encountered a similar issue and knows what might be causing it.
