nathanapffel Posted February 3, 2023 Share Posted February 3, 2023 I'm meshing a FLIP sim and trying to get a @w attribute to use with motion blur. Is there a way to calculate w from v on the simulation points for instance? Or does w need to come out of the FLIP sim? Quote Link to comment Share on other sites More sharing options...
bunker Posted February 4, 2023 Share Posted February 4, 2023 Check out the trail SOP, compute Angular Velocity (w). You'll need id and N https://www.sidefx.com/docs/houdini/nodes/sop/trail.html 1 Quote Link to comment Share on other sites More sharing options...
