  1. Thanks to help from hoomans on the SideFX houdini forum, I have exported a textured model from Maya 2022 to USD, then imported into Houdini 19 as a LOP network. Unfortunately, the materials have come across with only the base color texture maps as a constant shader. I have to replace these basic shaders with MaterialX shaders, with separate texture maps linked to base color, metalness, specular_roughness, and normal. The attached image shows a MaterialX that I manually rebuilt and applied to to the screen-left spherical tank. Is there a procedural way to search and replace all the basic shaders with MaterialX shaders, and re-wire all the texture maps? Thanks
  2. How do I use MaterialX - Worleynoise3D in Karma? Not supported? I can't find any information anywhere. Other mxlx 2d 3d noise works fine. mtlxUsdPrimvarReader(vec3 rest) --> mtlxworleynoise3d(position) --> mtlxstandard_surface(basecolor) ==> Black mtlxUsdPrimvarReader(vec2 st) --> mtlxworleynoise2d(position) --> mtlxstandard_surface(basecolor) ==> Black
