Hey, guys. Can you please tell me if anyone has encountered this problem in Karma? I throw textures format <UDIM>, and for some reason goes like this display in places, and it is not everywhere. I have already changed the environment variable in houdini.env . I added texture limits there, i.e. increased them:

HOUDINI_TEXTURE_MAX_UDIM = 999999
KARMA_XPU_MAX_TEXTURES = 999999
KARMA_XPU_MAX_TEXTURE_FILES = 999999

Checked through cop-network that each texture is working, well loaded individually, but why the fuck it does not load together or rather loaded, but like this, a huge question????? I removed spaces in the names of textures everywhere in the names of textures, does not help, changed some names and removed the format raw/ACES-ACEScg and the like. Why is it so I do not understand.

It works as expected in Karma CPU? If yes, probably best to contact support.

It's not a recent question, but I've got the same issue. The problem is the UDIM sequence of the texture which do not respect the standard UDIM naming.
For example:
- XXX_panels_BaseColor.1101.exr
- XXX_panels_BaseColor.1102.exr
- XXX_panels_BaseColor.1103.exr
- XXX_panels_BaseColor.1104.exr

are not a UDIM standard. So it's working with Karma CPU but not with Karma XPU.
The solution is to change UV to other place inside a correct UDIM naming.
In this case, you can offset by -10.0 all vertices with uv.y > 9, and renaming these 4 textures by 1001,1002,1003 and 1004.exr
