Brief look at texture overrides in Houdini 20.5.278 when rendering with Karma and the Principled Shader as well as Karma and MaterialX. Included is a tiny look at USD and the command line tools with husk.
***With MaterialX there is another method I have added to the sample files 21.0.440. It works locally - the original will work on a renderfarm.
