I would really appreciate help with doing the simplest possible volume render using RenderMan in Houdini. I always just get a black image. I think my issue is that I don't know how to set up a volume shader… A sample .hip file, or just telling me which nodes to use, would be very appreciated.

Some more advanced questions that I have, if you're feeling especially helpful:
* How do I render a VDB?
* What is the difference between the “RenderMan (rib)” and “RenderMan RIS (ris)” out nodes?

Hi take look at renderman forum
