We are still working on connecting renderman shaders to katana, but we can launch renders from Katana using renderman. I am also working on making it work in Houdini so that everyone can familarize themselves with renderman in an environment that they know.
This is a scene I created. All the objects are alembic files. The animation and everything works. I can put lights in the scene, and I am studying how to do shadows, and shadow passes, as well as global illumination if we want to go that route. I am also working with the CSR's to set the appropriate environment variables so that we can access the materials from Katana.
