Just for fun i simulated 2 High-res fumeFX explosions.
It took about 10 hours to simulate the first one
and 15 minutes rendering per frame !!
(on my old dual core mashine)
The second one took match less time to simulate and render..
next i did a very fast compositing in after,
I didn't added any extra details, just the explosions,
so its not perfect result but i still like it..
hope you'll engoy it too.
