This page provides information about the V-Ray Object Select Render Element in V-Ray for Houdini.
Overview
The Object Select Render Element stores only the object(s) called out with a specific Object or Material ID.
This effect is reversible to create a render element that excludes a particular object or objects according to Object or Material ID.
When rendering this element out, it will also include a filter and alpha passes separately to help make it easier to use when compositing.
