TextureMaterialLibrary LOP - Shading Problem July 20, 2026, 7:04 a.m.
First of all, big fan of the new TextureMaterialLibrary LOP, really like the convenience and workflow this offers.
However there's one issue I can't figure out;
When I assign the USD Material created in the COP network to geo, it breaks the shading and instead of smooth shading the shading becomes 100% hard and the geo becomes super facetted. I have tried messing with different USD vars but couldn't find any way of getting back smooth shading in the Vulkan viewport. Rendered in Karma everything displays fine but the look in Vulkan is very annoying to work with.
Any ideas are welcome
EDIT: Is it only me or does "Shift + Enter" to edit property in Solaris simply not work?

Karma Shader Precompilation H22 July 18, 2026, 9:20 a.m.
Anyone else experiencing issues with the Karma shader precompilation in H22? It first took absurdly long (7h or so on an RTX4090) and it then ends with this error:
I've never had any issues with precompilation in H21 so not too sure what to make of this.

H22 Wayland on Linux support? July 16, 2026, 3:54 p.m.
Oh man, that's a bummer that Wayland is not supported. I think this is a must in 2026.
