Startup error with SideFxLabs - Error reading CPIO data Feb. 20, 2026, 5:09 a.m.
Hi,
I installed H21 596 and as soon as I try to load Labs with the same version I get this messages. This results in missing recipes, any idea what this can be? It doesn't matter which version of labs I install, all throw the same error.

How to add a user defined MaterialX compound in Solaris? Dec. 11, 2025, 3:34 a.m.
Ah, I think the sidefx docs will help a lot. Thanks a lot.
A reference node can help but I'd prefer to have a similiar workflow as in maya where I can simply add a mtlx compound node and add to the mtx seachpath. Then I can use it alongside with the standard mtl nodes in the shader setup.

How to add a user defined MaterialX compound in Solaris? Dec. 9, 2025, 4:46 a.m.
Hi,
I created a MaterialX compound node as blabla.mtlx file. Now I want to use it in Houdini. In Maya I can simply use the MATERIALX_SEARCH_PATH env variable and I can use my node. In houdini the node is not visible at all. How can I use my own nodes in Houdini Solaris?
