For my wall I wanted to practice my texturing a bit, so I made a cobblestone wall, with the intent of it looking like it would fit well in a PS2 game. I made sure both the texture and the wall model itself are seamless - got a bit carried away on this one! Even made my own custom normal map for it!
Note: Texture is intentionally low resolution, to fit with the PS2 theme. I’m making textures for all of my dungeon assets, and all of them so far are either 256x or 128x
