So has anyone ever had to do a perforated brick wall like the one in the example? I am wondering if it's better to just manually cut a texture and create an opacity map or is it better to create geometry and apply bare clay material of some sort to look like a piece of brick. The former method seems to be more flexible in case I need to adjust any settings of the wall. The latter on the other hand could look more realistic imo so I can't make up my mind. What are you experiences?
