I have a project where textures that were working just fine in Houdini 20.5.278 with MTLX in Solaris are now showing up with weird glitches. (see attached screenshot)

I even disconnected the image textures and just tried it with an mtlx standard surface with white base color and the problem persisted.

I tried closing and reopening the scene view to see if it was a bug, but nothing has changed.

What else should I try here?

thanks,

Did you took a look, as what non desirable attributed had been smuggled into the SOP net? It could happen accidently by a miss click in the SOP network. After you dropped an attribute delete, try to regenerate the geo's normal attribute. Also take a blink on a normal render VAR path - what it shows on the problematic field. I know these are simple suggestions, but I'm sure that the geo has something not wanted. The mentioned version worked well on my side with old projects.

Thank you Polybud!

Good news. I fixed the problem by adding a time shift set to frame 1, and then attribute copy for the uv attribute on vertex back to the animated geo.

I appreciate the suggestion to check the render VAR path. I will keep that in mind in the future.

thanks!
