Just thought I'd share some progress I have made, decided to make some textures for the RedPower machines, as they seemed the most interesting. I apologise if anyone has already started on these, but here's a quick pic:
I tried to use textures straight from the terrain file to ensure they all blend in. I'm quite happy with how the teir 1 machines turned out, but wasn't really sure on how to proceed with things like the brass, and so ended up just putting a noise texture on the original parts (which I believe credit goes to Vattic's Faithful).
The texture sheet can be found here, so feel free to use it if you like
