cwalrus Posted April 18, 2016 Share Posted April 18, 2016 Hi people - I need a grain sim to happen, and then slow down in time and freeze. In other particle sims I just animate the Timescale on the solver to 0. For some reason it doesn't work with a grain sim. Please see attached. Is this a bug? As a work around I've tried adding a POPDrag node, and animating it greater and greater, but that also never seems to bring the bloody grains to a halt! Any advice greatly appreciated. Frankly I could do the same thing with just particles, but I love the clumping that grains does.... GrainTimeScaleFail.hipnc Quote Link to comment Share on other sites More sharing options...
Atom Posted April 18, 2016 Share Posted April 18, 2016 (edited) I noticed the same thing in the FLIP solver for H14. If you dive into the HDA look for TimeScale parameters on every single node. Some of them will be linked to the top level time scale via expressions and some may not. That is where the disconnect occurs. All the fields in the HDA may not be receiving the animated value. Each TimeScale field inside the HDA should also be set to Set Always instead of Default. When in Default mode TimeScale (or any parameter) is only evaluated on frame 1. Set Always causes the parameter to be evaluated on a frame-by-frame basis. Edited April 18, 2016 by Atom Quote Link to comment Share on other sites More sharing options...
