Common uses
The Render ID Render Element is useful for isolating geometry in a scene. This means that items can be isolated by use of a matte created from the solid colors within the Render ID pass. Exact RGB values for any object in the scene can be looked up, if the XML report is saved. In the example, the leather ottoman is selected using the Render ID RE, and it is color corrected. See the render before and after compositing.
