byronfillmore Posted February 23, 2017 Share Posted February 23, 2017 Is there an expression I can use in the Delete SOP to delete 5% of the points every frame? I'm stuck on this one. Any advice would be appreciated. Quote Link to comment Share on other sites More sharing options...
rich_lord Posted February 23, 2017 Share Posted February 23, 2017 Yes, just write rand(@ptnum) < 0.05 in the expression field of a delete sop. Heres it is set up. delete_points.hiplc 3 Quote Link to comment Share on other sites More sharing options...
rich_lord Posted February 23, 2017 Share Posted February 23, 2017 Oh, maybe you meant you want it to delete 5% each frame. If you want that, you just add in an @Frame attribute like this. rand(@ptnum) < @Frame * 0.05 delete_points_time.hiplc 3 Quote Link to comment Share on other sites More sharing options...
