Is there a possibility to reduce grain sim ram usage?
im doing some fiddling based on the test scene, and when i crank up the detail (reduce voxel size) the ram usage goes through the roof.
ive just got the torus object enabled. the scene defaults are more like a pile of marbles, and im trying to get closer to wet sand (playing with clustering)
however reducing the voxel size from 2 to 0.5 is the best i can manage.. it uses all of my 64 GB ram. its still too low res to be convincing, even as a fairly small sand patch.
not having done a direct comparison i cannot say for sure, but it seems that tyflow uses MUCH more ram to sim than the tests i did in houdini a year or so ago...
i remeber in houdini there was also a trick to "upres" the sim.. something like replacing each grain with a small cluster of grains, which helped a bit... i guess i could do similar here...
any other tricks to reduce ram usage, or plans for future improvements in this area?
thanks!
