isah_voodoo Posted November 2, 2019 Share Posted November 2, 2019 Hello, I have a question about bringing in points from sops to dops for a FLIP simulation. When I add velocity to the points in sops, the points get an offset in dops based on how strong that velocity is. If I were to multiply the velocity in sops by something strong like 100, it will be offset even stornger in dops. I am trying to get the point positions to stay in there original position coming into dops. I know how to fix this issue in a particle netowrk setting the "Jiter Birth Time" to "none"..but how would i fix this with a FLIP sim ? I will attach a scene file and screenshots for anyone that wants to take a look. Thank you. flip_point_offset.hip Quote Link to comment Share on other sites More sharing options...
vicvvsh Posted November 3, 2019 Share Posted November 3, 2019 Hi, look at "Time Offset Scale" parameter of Volume Source dop, particles tab. Quote Link to comment Share on other sites More sharing options...
karanjaura Posted November 3, 2019 Share Posted November 3, 2019 also you can use particlefluidemitter inside Dops, to source from your SOP points. flip_point_offset_v01.hipnc Quote Link to comment Share on other sites More sharing options...
isah_voodoo Posted November 4, 2019 Author Share Posted November 4, 2019 @vicvvshThis is exactly what I needed. Thank you @karanjauraThanks. Your file is not working for me. I think that is a digital asset you installed. Seems interesting though. Where did you get it? Quote Link to comment Share on other sites More sharing options...

I'm using 17.5.173 and I do not have it, so must come with a later build https://www.sidefx.com/docs/houdini/nodes/dop/particlefluidemitter.html Quote Link to comment Share on other sites More sharing options...

The docs state 17.5 but I think they removed it in 17.5 then and the docs page is just there for legacy purpose (because until it really is removed the operator is just hidden by default) Quote Link to comment Share on other sites More sharing options...
