So I've added a few textures, will probably go back and revisit these later or and tidy them up a bit. Nice to get a bit of colour on there. There's a normal map on the roof, but as far as I can see it's not really affecting the texture that much. I mite try it in unreal and see how it looks. Still need spec maps for certain bits, but they don't seam to do that much in unity either.
