Water spray / foam suggestion

[Mikla]

Hi,

I'm trying to simulate a whale breathing/blowing out air and water spray out of his blow hole but came across with couple of issues:

First i've tried with xparticles sprites. It does render the sprites. It does the motion blur as well. But the mb occurs only on the edge of the sprite planes. (i've tried it with solid color) The spray texture isn't affected by the blur. (using transform mb)

Tried it with realflow but it takes too much ram in GPU (when using mb) and the mb looks weird as in the velocity occurs in every direction (maybe a mapping issue?)

Do you have any suggestions doing this sort of effect? Maybe i should resort to more simple setups like tp or cloners/metaballs?

Thanks.
