This is from an email I got from them today. Confirming what I already knew really.
We have received many questions about Non-Commercial RenderMan, particularly about what it can do and who it is best suited for. Here is a short summary of what you can expect.
First as a reminder, RenderMan is not a standalone animation system. It requires a modeling and animation solution to provide it with scene data to render photorealistic images. Well known CG authoring solutions compatible with RenderMan include Autodesk Maya, Maxon Cinema4D, Side Effects Houdini, and The Foundry's KATANA. In addition, familiarity with computer graphics (including modeling, animation, lighting, and rendering) is important to properly utilize RenderMan's capabilities. If you are unfamiliar with the process of creating and rendering images, we suggest first becoming familiar with one of the above solutions. RenderMan itself provides advanced tools for shading, lighting, and the final rendering of visual effects.
Doubt I'll be able to figure this out enough to use it. I haven't gotten far in Maya. :\ Cant even find the render button. I know what it looks like, its supposed to be a clapper icon, but its nowhere to be seen on my copy.
