Renderman. The question is in subject, here are some additional details I was able to find so far:
In rendering parameters for prman, there is "reference camera" under "dicing" category.
But I still can't figure out how to set it up. In this parameter, I can choose between "world camera" and "frame camera", but i couldn't find a way to mark a camera itself as "world" or "frame".
Looks like there are some modifications in rib structure that need to be done to make this parameter work. And I can't figure out how it's done in Houdini.
It's the 3rd day I'm trying to find a solution, but I'm stuck with no success. Could anyone help with it, please?
