CeeGee: Thanks Igor! Better/larger ones are en route, once I get some sims finishes
Thank you for the elephants! That was such a nice looking test, technically and artistically. BTW, did you render that with mantra? Was the meshing done in NAIAD, I assume?
dynamoanders: Thank you! Yeah, I used the Viscosity shelf tool to turn on viscosity. Then on the flipfluidobject, under the Physical tab, the Viscosity parameter is at the bottom.
Some observations so far:
- Turns out that the density strongly affects the viscosity settings. For example, these teapots are about 1 meter square, and their density is at the default of 1000. This meant that my viscosity settings for the three teapots you see here are 1000, 36642, and 72285. I'm resimming at a lower viscosity, 9500 (that's why there is only the really low "1990's" resolution render attached
That was something I wasn't aware of before! So it was really cool to learn.
- I'm using a Phenom II X6 to sim/render these, and for FLIP Fluids, there seems to be lots of time that only some cores are being used, which is where the i5/i7 CPUs seem to be stronger; but mantra really uses all cores well; I never really saw the usage drop from 100%
- Using some of the tips found here
, I re-rendered the large still. Interestingly, I noticed the SSS noise decreased dramatically, but the noise on the plain white shader increased (I did tweak the ground shader a bit; perhaps that caused it?)
Thanks for the encouragement!
