multiple fume grid rendering

[bdemetz]

Due to time constraints, we ended up rendering all the explosions individually. In this case, they ended up blending together ok. Actually it took exponentially less time (i.e. 1 blast took less than 1/3 the time that 3 would have together), though it would have been nice to have blasts shadow each other.

re: Does this happen if you render locally ?
a: i'll need to test that - deadlines, deadlines ; /

Do you loose self-shadows as well ?
a: looks like it

Are you sure you do not run out of memory ?
a: i'd like to say yes but if it's hovering around 6gb out of the 8gb our farm machines have, it could be trying to spike up and run out - not sure.

If you resim with double grid spacing (a lot less memory consumption), does it
render okay ?
a: havent' been able to try this either.

Since i have no other tests results to offer, perhaps i can just ask - if there is enough memory available, is this something that is supposed to render fine with no popping issues?

Thx again Kresimir
