I'm interested in creating my own textures for my map. Yes, I have used google and I know how to create textures from photos, but the thing that strikes me as odd is that alot of the map textures used in trem and other quake-like games don't appear to be made from photos. At least, not entirely. While the textures are obviously synthetic, they often have a very natural feel to them that would be difficult to do just by using an image editor, i. e. lot's of scratches and bumps and fine detail. Do they blend the photos into the texture and then draw the outlines over it in a separate layer? How exactly do they do it?
Help would be very much appreciated
