Skybar Posted October 28, 2013 Share Posted October 28, 2013 Havent looked at your hip, but from the flipbook it seems like the problem is your collision geo. Quote Link to comment Share on other sites More sharing options...
Aeonx21 Posted October 29, 2013 Author Share Posted October 29, 2013 yes I do know that that is the problem, I have tried alot of times but im not sure what is causing it Quote Link to comment Share on other sites More sharing options...
teratera Posted October 29, 2013 Share Posted October 29, 2013 Hi, If you could provide your geo obj or lock the node in hip file, that'd be great You obviously have some issues with using collision volume, I'll be glad to help. Quote Link to comment Share on other sites More sharing options...

teratera Posted October 29, 2013 Share Posted October 29, 2013 Here you go. When you're experiencing problems with collisions just inspect collision field through the FLIP object visualisation options. You could see that your field lacked resolution and was patchy. Which is solved by turning on separate Collision resolution option on FLIP object and also by lowering particle separation (decreasing Grid scale also helps). Yes, and also sometimes you need thicker SDF, so you have to optimize. You can read all the tips in help I used classic SDF with Static object which gives me better results, but I included a VDB example as well. Which you can see kinda works, but you need more resolution for accuracy. Also I think there's no collision velocity on a 'classic' example, so that'd be preferable. https://www.dropbox.com/s/kryz836v46n4dn6/1_fix.mp4 1_fix.hipnc 1 Quote Link to comment Share on other sites More sharing options...
Aeonx21 Posted October 29, 2013 Author Share Posted October 29, 2013 Thank you. The funny thing is I adjusted almost every setting in the static object and the flip slover, and some in the flip object, I will have to visualize every field next time. Thanks again Quote Link to comment Share on other sites More sharing options...
