rkoomera Posted April 15, 2021 Share Posted April 15, 2021 Hi! In the attached hip file there are a bunch of spheres generated using the pig head geo and connected to a solver with VDB advect. Is there a way I make these spheres grow inside the pig ahead so that when they grow to touch the surface of the pig ahead, they should just collide and deform? I tried converting the pig head to a vdb but I think it needs to be hollow from the inside for it work. Thank you so much for your help!

ryew Posted April 15, 2021 Share Posted April 15, 2021 Perhaps try using VDB Convert From Polygons on the pighead and set your VDB Combine to "SDF Intersection" instead. Having said that, if you are looking for the effect of small balloons, this is something Vellum should handle easily and convincingly, search for the "pressure" threads on here or check the SideFX Masterclasses on Vellum for examples (and I'm sure google will show plenty more videos) 1 Quote Link to comment Share on other sites More sharing options...
rkoomera Posted April 15, 2021 Author Share Posted April 15, 2021 @ryew that kind of worked! And I'm pretty sure vellum is the way to go. I will look into it. Thank you so much! 1 Quote Link to comment Share on other sites More sharing options...
ryew Posted April 15, 2021 Share Posted April 15, 2021 No worries, have fun with vellum! Lots of fun examples to play with out there Quote Link to comment Share on other sites More sharing options...
