draganbaja Posted September 1, 2016 Author Share Posted September 1, 2016 (edited) Tnx, this is exactly what I need Can it be done with flip fluids? Edited September 1, 2016 by draganbaja Quote Link to comment Share on other sites More sharing options...
stevegh Posted September 1, 2016 Share Posted September 1, 2016 You don't need FLIP at all. All you need is a simple setup to move a point along the surface flow which can be calculated with the SDF gradient and some cross products to get your up and right directions. Then you can add some randomness by rotating around the gradient direction and add a trail sop to get the streak. Assign pscale based off of ptnum/numpt and VDB from particles the result with an SDF smooth and voila. I was able to get this result in a couple hours and while it needs tweaking it should get you started. drips.001.hipnc 7 Quote Link to comment Share on other sites More sharing options...

HGBarca Posted March 14, 2018 Share Posted March 14, 2018 Hi Steve, This looks great, but do you know why the viewport gets very slow when working? Quote Link to comment Share on other sites More sharing options...
