This compound lets you access the ID of a point in a mesh, or a particle in a point cloud. Particles have a Point ID for each point that you can access directly using a Get Data node, but polygon meshes do not have this.
This compound is used in compounds that need the ID of a particle to generate things like random values. If you use this compound, rather than accessing the point ID directly, any compound you build with it can be used on both meshes and point clouds. Plug its Point ID output into any port that accepts integers per point of a point cloud.
For more information, see Working with IDs and Indices [ICE Fundamentals].
