Hi,
I've been trying to render UDIM textures in Karma XPU(Beta) but it never reads UDIM.
When I switch to CPU instead, it's okay. No problem so far(it reads UDIM).
However when it comes to XPU, Karma renders without textures.

Does anyone know if XPU support UDIM?

Thanks.

UDIMs are supported, but (by default) capped to 10 x 10.
If you need more, you can set some environment variables (KARMA_XPU_MAX_UDIM_U and/or KARMA_XPU_MAX_UDIM_V) to extend that, but handle with care!

Does your model exceed these limits? If not, you may have run into a different issue.

UDIMS work fine in XPU, always have.
I suspect you're using a strange filepath format (or perhaps the files are not stored on disk correctly)

This works for me

Filepath = "$HIP/tile<UDIM>.exr"

Filenames
- tile1001.exr
- tile1002.exr
- tile1012.exr
- etc...

Also... are you using MaterialX? (ie mtlximage VOP{) or USDPreviewSurface? (ie usduvtexture VOP)
If not, that might also be your problem.
