Did you all see Georges bryce FX in the store? I got to try them out and even though I don't post a lot in here ( not real good with bryce yet!) I did a little pic to show you the fire effect, I think its one of the best( lol not my pic, the fire!) I've seen. And there are some sky presets, rain snow etc!
