Set ID Node
![Set ID node.](../../../_images/node-types_GeometryNodeSetID.webp)
The Set ID node fills the id
attribute on the input geometry. If the attribute does not
exist yet, it will be created with a default value of zero. The ID is also created by
the Distribute Points on Faces, and it is used in
the Random Value Node and other nodes if it exists.
The input node for this data is the ID Node.
