Here is some test footage of my House blowing up for my series GONE, it was made using ParticleIllusion. In the scene two people will be in the room that contains the bomb.
Sorry for the quailty on the Youtube one. The Putfile version has MUCH more detail.
It's only 1-2 seconds long and is Dail-up friendly
