Ravs, maybe it would be worthwhile to do a tutorial on creating tiles.
Here is a tiling city building texture (in shocking pink so it's easy to select the colour with the magic wand and change it to a colour of choice). It's intended to be used for those parts of a city where the buildings are crowded and close together.
Good idea, I'll give it a go. May be a while though as I'm very busy at work and on hols next week.
p.s. is that your eye in your avatar? Are you a Fremen?
Nope, not my eye. I actually wanted to use my own eye, but I haven't gotten around to it. But yes, it is photoshop'ed to give it that Fremen look.
