pamplemousse Posted November 18, 2018 Share Posted November 18, 2018 Hi, I'm trying to loop a FLIP fluid simulation, it's a simple water container with various floating objects interacting with the water. I need to loop the sim and didn't have any luck with the "Make Loop" node from the Games shelf. Anyone know how to get this to work with a fluid sim? Thanks!

jerryace Posted November 19, 2018 Share Posted November 19, 2018 You may try to key animate curve with particle scale before convert them to SDF,first key value is 0-1-0,second is 1-0-1. Quote Link to comment Share on other sites More sharing options...
Neronie Posted November 19, 2018 Share Posted November 19, 2018 (edited) I've had decent results by creating an sdf of the simulation, mixing it with a timeshifted copy of itself so that it loops seamlessly, and then meshing it. Obviously results may vary as you wanna have the start and end as similair as possible; some blending artifacts are going to be visible. Perhaps a better solution could involve calculating some kind of difference velocity field towards the end of the sim by comparing it to a timeshifted copy of itself, and then use that to advect the present-time sim... Then blending the two results as above. Just a thought though, wouldn't really know how to set this up properly.
