I'm using the point replicate node after a delete node and want to maintain point id's after the delete so the point replicate doesn't change frame to frame. I can set a constant attribute and carry that over but how do I write to the id attribute or keep it stable?

A: Set the id attrib yourself… derp. I had tried that earlier for some reason and it wasn't working. This would be a handy feature for the delete node.

What if you color your original points red. Then you point replicate and color those points blue. Then your delete only red colored points? The point replicate should remain stable frame to frame because they were generated before the delete.
