I do tend to agree with you on the texture. I have the same problem all the time trying to make bryce built buildings look weatherworn and aged. What we need is a source of building textures whereby we have a photo texture of an entire wall, not just a small section that needs to be tiled. Does anyone have any ideas where such could be found?
