Image RemovedThe Object Select render element allows you to extract the contribution of one or more objects to the scene. The objects can be selected based on the object ID or material ID for objects with the same material.Render Channel 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.
