Realflow Particles For Water Splashes
Posted 14 April 2008 - 08:06 PM
The result is not brilliant ( not suprising for a beginner) and mostly the water effect is not that good but when there are violent reactions i think it works. The technique would be good for water splashes, say for example sea spray crashing over a ships decks, without all the hassle of creating meshes
The technique was to render out 800,000 bin particles in realflow ( at about 30 GB ??) then bring these into krakatoa and convert them to prt files at 5GB, i then rendered out 10 partitions ( a couple of hours) to get 8 million particles
Krakatoa then renders them with shading ( about 30 secs a frame) and can take scene objects into consideration with auto masking. It can also do particle shadows on geometry but i did not try this. There is some odd masking going on on the right hand pillars, not sure why this has happened
Because this is a large scene it could probably have done with more like 50 million particles and it would have been better if the initial realflow bin sequence had stated out with more ( say 5 million) but the 800,000 took 20 hrs to sim 400 frames!!!

But loading realflow BINs into Max and running partitioning in Krakatoa does NOT really perform any randomization to the particles. So I would expect that you would get 10 times the same particles, which would be a waste of time (not to mention disk space). Partitioning relies on changing the random seeds of the particle system, but AFAIK a BIN sequence loaded into 3ds Max has no way to be affected by it.
That being said, using the new Krakatoa 1.1.0 Particle Flow operators, it would be possible to introduce a randomness to the particle positions, although it can cause some fuzziness in the final rendering - check out this tutorial:
Of course, I might be missing something...

i will try the pflow method when i get acess to MAX again
