You can of course, do as you wish with the textures, as I will be including the UV map and a sample texture with the sets.
While I still have to finish the beta build of the rails and write instructions, I've since started a city road design. As roads tend toward 90 degree angles, there will be oddly shaped elements:
Tentatively I'll be designing around a 5-Hex 'block', or 150 meters, which is a little larger than a 'standard' New York block (130 meters or so). Of course all elements will be modular.
At the moment I'm planning 1,2,3 hex sections (center-to-center measurements, and cross-hex as shown below). A bridging section with ramps, a level rail crossing and maybe curved sections, depending on how I feel.
Generic city buildings may be next, although I'm frankly not certain. Lets get past this first.
Enjoy,
Tirick
