## **Common Uses**

---

The Object ID Render Element is useful for isolating geometry in a scene based on the Object ID. This means that items can be isolated by use of a matte created from the solid colors within the Object ID pass. 

 

## **Setup**

---

Create a [VRayObjProp ](https://docs-chaos.atlassian.net/wiki/spaces/VRAYNUKE/pages/110624956)node and connect it between the object node and the scene node. Set the **Object ID** to the required value. Note: each number corresponds to a different color.
