hello, i am in the process of making this into 3d. However im not sure on how to go about the roof tiles with texturing them later on in mind. Im aware of the technique where you move the uvs over to the next coordinates to use the same textures, but i also want some of the tiles to have unique textures such as weathering effects and cracks etc so they dont look completely identical. How would one go about this from start to finish? Any advice would be greatly apprieciated.
