MediaFire File - Allods .psd Texture Package
You can change the colors, the styles, so on and so on of these textures and I'll help you put them in your version of the game with an add-on.

The only requirement is that you keep the texture sizes in powers of two. Use blank space for the remainder of the size. (Examples are in the textures provided.)
Process: You recreate/design/whatever the textures and hand 'em over. I analyze the implementation requirements, (hopefully don't need to) modify the texture sizing, and write some LUA code to replace or overlay the similar texture in the game.

Add-ons: These .zip contain .pak files, just place them in your AllodsOnline/data/Mods/Addons/ folder.
