The scale of the stations means that those blocks are very building-like indeed. I'll have to go back to the texture to check.
I have no idea how to scroll the blue pixels in the shader and no way to test the code. I'll concentrate on extracting the blue from the diffuse map and make some height-maps - then pass it over to you dear griff ;)
Random decals are interesting - theres space for them over the dock in the isoc and coriolis models. Simple grunged shapes, not always English?
Perhaps the isoc could be newer? It appears in very high tech systems.
Lights: the isoc can have rows of lights set into the smooth triangles, probably oriented from the top/bottom corner and to the middle of the opposite face.
The dodo would be harder, which is partly why I was interested in the blue lines version.
The thing that originally attracted me to lights on stations was an effect I noticed in the griff-coriolis - when the sun shone over the lights, they were washed out and you just saw the dimple where they were.
It's my birthday today (8th) so I redid my old katapo model as a feel-good. See
the original thread. Now I know how to do it properly of course...
I have another paper due on the 15th - but I'm half way through it, so I should be able to deliver on those stations by Saturday (my time) before I really have to get stuck in.
