Hey guys,
Quick question about deleting scatter points. I have a character walking over a grid and transferring red to scatter points on the grid. So his foot steps are in red. His foot stays down on the grid for about 2 seconds
before he continues his walk cycle. The red particles are piped into a popnet which is emitting particles. Problem is those red points keep emitting particles and not just a burst. I'm trying to either delete those red points almost instantly but long enough for the popnet to emit once, or emit only once from the red points. He does this throughout the animation, so I don't think I can use $FF. Kinda new to Houdini, so maybe I'm not thinking about it correctly.
Thanks
