# Instance ID Node
|
|
|
|
## Description
|
|
|
|
When Unity renders with GPU instancing, it assigns an **Instance ID** to each geometry.
|
|
|
|
Use this node to capture **Instance ID** values in [`Graphics.DrawMeshInstanced`](https://docs.unity3d.com/ScriptReference/Graphics.DrawMeshInstanced.html) API calls.
|
|
|
|
When Unity does not render with GPU instancing, this ID is 0.
|
|
|
|
When Unity uses dynamic instancing, instance IDs might not be consistent across multiple frames.
