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 also includes a filter and alpha passes separately to help make it easier to use when compositing.
