Artifacts appears in Houdini XPU - UDIM Issues April 25, 2024, 8:55 a.m.
Pretty weird bug to reproduce.. So I did a simple scene with a mesh from kitbash. I only connected a normal-map texture.
When I used <UDIM> the artifacts appear in XPU. NB: The textures for the tests are not related to the mesh but I got the same bug with my working mesh that have correct UVs and UDIMS.
I did the test with a folder of 80 maps(normal)and the bug appear but when I connect half of the textures, there's no bug anymore.. The bug also disappear when I reduce the mesh polygon by deleting half of the mesh for example.
I did some tests with .abc and .fbx and it's the same issues

Artifacts appears in Houdini XPU - UDIM Issues April 23, 2024, 11:45 a.m.
Hi,
I got an issue when I render with XPU that seems to be related to udims.
On huge assets(building) it seems that the UDIM workflow doesn't work properly and break the render with some artifacts.
The asset has a mtlxStandardSurface and everything is working fine in houdini GL or CPU but as soon I used XPU render, the mesh disappears and create some artifacts in all the scene.
After some tests it seems to be a UDIM problem as it only happen when I used <UDIM> token in my texture path otherwise if I used the texture path "1001" the XPU work correctly.
I'm not seeing any errors in the logs.
Is there any solution or update that would fix that issue?

Houdini 20 - OCIO - ACES 1.2 March 14, 2024, 3:34 p.m.
Hi,
In Houdini 19.5, I set up the OCIO with the ACES 1.2 to houdini.env. I saw the correct OCIO 1.2 config file loaded in Edit>Color_settings>Color_correction and I saw in Render View in Color Correction bar that ACES + sRGB is being used. Everything was working properly.
In houdini 20, If I set up the same way, that doesn't work. The previous render in the gallery and the new one are wrong and didn't match the colorspace that I have with aces 1.2 in houdini 19.5
Whatever I do in the new OCIO editor that doesn't fix it. even when I changed exr colorspace to ACEScg to fix the snapshot that doesn't work.
So how can I fix the gallery snapchot with the correct colorspace to have the same render saved in the 19.5 and 20 and how to add the ACES 1.2 properly on in the new OCIO setting ?
Thanks in advance
