papsphilip Posted February 9, 2022 Share Posted February 9, 2022 i am trying to use the volume gradient - volume sample method to keep moving particles inside a volume. The particles move freely with a noise but as soon as they reach the edge they should turn. Doesn't seem right so far sdf_bounds.hip Quote Link to comment Share on other sites More sharing options...

Yader Posted February 9, 2022 Share Posted February 9, 2022 (edited) You could also use the pre made pop advect by volumes, calculate the vol gradient beforehand and just set the velocity scale to -1. sdf_bounds_Yader_03.hiplc Edited February 9, 2022 by Yader 3 Quote Link to comment Share on other sites More sharing options...
