A more refined and detailed version of a test I created earlier. Sim time: 2h on i9 7940X only for the flip sim, iso surface and white water simulation was calculated on the fly while rendering so you can add another 2h for this. Render (Redshift): 2-5min per frame on 1070&1080 I had to do almost 5-10 tests for both simulation and rendering until I achieved this final result, oh man our specialty needs alot of patience and hardware power. I still have some flickering going here and there tried to clean them in comp.
