Hi, what's the best way to read Copernicus into a renderman shader, I saw the compatibility in the latest release but wasn't able to make it work adding the op:/Copernicus texture etc into a pxrtexture filename, thank you

The latest RfH builds do, I believe, allow COP-based texture maps. They are specified the same way you would do so for a karma shader using the "op:/path/to/cop" string in the "Texture File" parameter of a VOP, or Material Edit Properties LOP. This is something that needs to be implemented on the RenderMan side, so make sure you are using a version of RfH that claims to support this feature. Then build a simple hip file that gets it working with karma (using USD Preview Surface - a shader language understood by both Karma and RenderMan). Then switch to RenderMan. If it works in Karma, it should work in RenderMan too.
