Sure, the explosion itself is made of meatballs I just kept duplicating them until it fill the hallway. Then I added a material with R.713 G.309 B.202 or something like that then a marble tex with .588noisesize 6noise depth 22.60turb then in Mapto the settings were R. 1.0 G.708 B.372 I also activated color, alpha, and spec then for map input just orco and flat. Right behind the explosion is my particle explosion

Which worked nice with it via the alpha in the marble tex.
so thats pretty much it I dont think I could tell you how I made the particle exp because i dont know I just kept messing around untill I got it right their are 4 particle emiters for the particle explosion.
So thats it if I did a horrible job explaining it Im sorry.
