Star Trek Ship Design and Hull Texture

For the Hero ship of my joint fan series Star Trek Castaways I’ll need help with refining the model to it’s final shape with input from you guys, but that’s not the main reason I’m making this post, I want to develop multiple detailed textures for the hull such as the Pearlescent Hull Texture seen in Star Trek The Motion Picture, A Texture that shows the individual plates on the hull, Weathering textures, and scorch mark textures. Here’s the basic layout of the ship in question

here is an old tutorial on making the aztec pattern for the Dish http://www.meshweaver.com/tutorials/Aztec_Patterns.htm

There may be a way of generating it procedurally by now with nodes but I haven’t looked into it.
