Camangren Posted April 9, 2014 Share Posted April 9, 2014 Hello everybody! I was following the waterfall tutorial from the Side Effects webpage to make a simulation of water falling down some stairs. Simulating the fluid with more or less 2 million particles for 300 frames took me about 1 hour, but the white water simulation is taking 1 hour per frame even though I did a cache for the source to make it "faster", is this normal? I barely changed the defaults, basically I just added collision with the stairs. Thanks for your help! Quote Link to comment Share on other sites More sharing options...
Solitude Posted April 10, 2014 Share Posted April 10, 2014 No, that's not normal at all. How many particles are you generating? Depending on the scene of course, but I've had to turn down the birth rate quite a bit a few times. Otherwise, test without the collision object. Maybe you are you generating a super high res volume for the geo and that is causing the slow down? Quote Link to comment Share on other sites More sharing options...
Camangren Posted April 12, 2014 Author Share Posted April 12, 2014 I was generating over 100 particles per point. The problem was that I thought that the "life" of the particles was 5 frames, not 5 seconds, so in the end I had more particles for the white water than for the actual liquid. Now that I changed how muc the particles live it's simulating normally. Quote Link to comment Share on other sites More sharing options...
