Wireframe Shader inside Karma MaterialX Subnet? May 6, 2024, 3:56 p.m.
Hi
I tested most of the propositions but as explain by Jsmack most of the solution work only with a single object. Otherwise the faces of different sizes will have different widths/thickness.
I'm still looking for a solution to get a Wireframe that's working with "complex" assets.
If someone got another idea for my needs. It will be really appreciate

Karma XPU Artifacts with 4090? May 2, 2024, 9:24 a.m.
Hi
I have the same issues with my 2080, I thought that a new Gpu (4090) will fix the problem but as I read your post it will not..
I tested to add this envvars.
KARMA_XPU_OPTIX_SPARSE_TEXTURES = 0
It fixed the issues but Optix doesn't start (initializing) so very poor performance
I tried also with this 3 envvars. Same result
KARMA_XPU_OPTIX_SPARSE_TEXTURES=0 (default is 1)
KARMA_XPU_OPTIX_HQ_LINEAR_FILTERING=1 (default is 0)
KARMA_XPU_DISABLE_MIPMAPS=1 (default is 0)
Is there any other solutions to fix it?
Thanks

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
