sheiladoreen Posted November 27, 2019 Share Posted November 27, 2019 Hello there! Newbie here, to odforce but also to fluids in Houdini! I have spent a couple of days learning how to set up fluid sims with shelf tools and manually. However, it is still unclear to me how to use custom velocity for fluids. Unfortunately a lot of tutorials are outdated and don't work for Houdini 17. I've been trying to follow Andreas Glad's tutorial on Paintsplats. He uses the normals of a distorted sphere as velocity for his fluid to get a nice omnidirectional explosion of paint. Is it possible to do that in Houdini 17? (It is most probably, but I have no idea where to integrate that velocity information into my Dop Network.) I hope someone can enlighten me on what to look for!

sheiladoreen Posted November 28, 2019 Author Share Posted November 28, 2019 With help of some fellow students I found a workaround to get a paint explosion, using popattract and setting it to a minus value. However, I'm still wondering how to use velocity information from a sop for a fluid. 1 Quote Link to comment Share on other sites More sharing options...
DonRomano Posted November 28, 2019 Share Posted November 28, 2019 Hey, dive into the flip source and setup your velocity there using wrangles. If you have a file I can show you how it works if you want, Cheers, Quote Link to comment Share on other sites More sharing options...

ThomasPara Posted December 2, 2019 Share Posted December 2, 2019 (edited) You can make the particle field yourself and then source that. PaintBlob_fix.hipnc Edited December 2, 2019 by ThomasPara Quote Link to comment Share on other sites More sharing options...
