There are many options for rendering and some are obscure or for special circumstances. We support having multiple ROP nodes in Houdini so that you can tailor each one to your task, be it IPR settings, different display drivers for render passes, or useful changes you'd like to see as you render. Be sure to use the render controls of the ROP node you are wishing to view the results from. As an example, you could create a ROP node with settings designed for fast IPR and another for final production renders.

This document aims to help you navigate the differences as simply as possible.
