The Dynamic ID Generator assigns persistent unique IDs to points inside a SOP Solver.
Unlike @ptnum, which represents the current position of a point in the geometry list and can change when points are added, removed, or reordered, @id remains attached to the point throughout the simulation.
This makes it useful for tracking points across frames.
Fully customizable and documented
How to use:
Plugin your changing @ptnum points to get stable @id, done.
