So as a bit of an experiment - I thought rather than slapping photographic textures on this, I’d see if I could texture the whole thing procedurally. There are no image based textures at all here, it’s all just using the built in Blender textures, which also means I had to do absolutely no UV unwrapping!
In the past I’ve done weathering like this by hand painting onto the model. It’s probably turned out looking more stylised than something made with image based or hand made textures.
Anyway, the first image is just a black environment with some lighting, the second is lit with a HDR environment (OK, I guess that’s technically an image based texture…).
I’ll post the node setup for the main body in the comments!
