Smicksus Posted November 28, 2021 Share Posted November 28, 2021 Hi Magicians! I'm having trouble setting up my grain sim for a personal project I'm doing to get a better understanding of the mechanics in Houdini. In short I have a growing coral object which have to interact with my grains whilst it is growing. In my understanding what is going wrong. My vdb collision source is to jittery when it grows in my grains the vdb creates not smooth enough. I've tried adding a retime to my object to let it go more easy in my simulation but the problem keeps happening. If I go trough it frame by frame the vdb creates a surface and the next frame it is suddenly larger and that causes the grains to explode? Can someone please look into my .hip file to see if someone can fix my issue? I realy want to know the solution to this. I hope someone is willing to help me So much thanks in advance for the one that can help me with this. growing_object_grains.hip Quote Link to comment Share on other sites More sharing options...
