The pipes have procedural textures from the Bryce metal textures as well as the tanks. All the other textures are from image textures from all over the web. Some I used just as they were but most were tinkered with in Photoshop. Even the procedural textures were changed from what they were originally. If you guys want, I'll post some of the metal textures I used for this model so you can use them in the future.

Because I like to blow $%&# up.

Don't fear the night.  Fear what hunts at night.
