FlipFluids

Trying out Blender      Flip Fluids      – currently baking below lighthouse.blend sample file, 2-3 days so far, about 10 hours go go and 89Gb cache space used up!

Final space cost and rendered frame one, as of 5/29 6am [frame 0 rendered in 2.5 mins]

 

 

After 60 frames l got….

=====================

So far l have only been able to render up to 149 frames, then l get a cuda out of memory crash. I use both a GTX970 with 4Gb and a GTX1080 with 8Gb, l’ve tried with both and with each cards. Will keep you updated, meanwhile heres a render of the 149 frames
