So today I've been working hard on getting smoke and water working:
The Water and Smoke
(Smoke looks awesome when moving)
There are also these that I found (they may only be on 2011). There files already in maya and make an excellent explosion and fire. I thought maybe the explosion for when the meteor hits the dumpster, and the flames could maybe be used on the city during the shots to show damage. Only still images from the animation at the moment because my render is giving me an error, but I'll fix that.
