Textures

I'm going to manchester at about 6am tomorrow to try and get some city shots before it gets too manic, then off to salford and outskirts to try and get more grimey textures. I am concerned that because a lot of the scenes are indoors and as I don't know of any derelict houses round mine I won't be able to provide the whole set of textures from the pics tomorrow, but with some photoshop layering perhaps we can produce original images for the interiors once we know exactly what textures we need for the assets. Alternatively I found a few more free grungy texture sites yesterday that will help
