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 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.
