Smicksus Posted November 26, 2021 Share Posted November 26, 2021 Hi there, I had some trouble with my vellum grains simulation. As I use deforming geo for my collision (it's a collider from a growing volume converted back to geo) When the collision happens with the deforming geo the grains go all haywire. Adding subframes in the vellum solver doesn't help. The issue is that I have subframes in my grains but probably not in my collsion geo. I read I can achieve that with a retime node. Altough I have no clue how I actualy get subframes with that.. Do any of you have a good tutorial or can explain to me how this works? Oh and if you think I'm wrong with adding subframes to my collision geo, please let me know. I'm realy looking for any solution realy. If you're curious to what my problem involves please look at the provided HIP file. TLDR: How does the retime node work, to add subframes to a collsion source for vellum grains? example_sand(Houdini18).hip Quote Link to comment Share on other sites More sharing options...
