I got stuck here in a middle of an project and i can't find a solution.
My problem is : I have a grid of points , and an animated point running over the surface of the grid. My “running” point have an attribute that is transferred ( via attrib transfer SOP inside an Solver) to the grid points by an proximity radius.
then I use the transferred attribute to isolate only the grid points that are touched by the “running”point. But the @ptnum of the remaining points is changing. And i need the @ptnum to grow in the order detection ( @ptnum 1, 2, 3, 4, 5 etc)
why is that happening?
to understand better I've attached the scene file
