  10. popdrag - slower particle in selected radius

    Hey James! Sorry for my very late reply. I was quite bussy for long time. I fixed this problem by myself but it was done by very hard and crazy kind of way... I like your approach... thank u very much for your help!!!!!
  11. popdrag - slower particle in selected radius

    Thank u so much James, now it works! I added more "falloffs" and it works perfectly!!! Can I ask U one more time? I have problem to put particles just inside of the object (i mean not sliding on the surface, but flowing just inside of the geometry). I tried poplimit node, but this works just like BoundingBox, and I need to defined it by my specific geometry... maybe u can help me fix this too... And Thank u again for your previous explanation and help. cheers pop_inside_issue.hip
