I´ve a room, which I UV unwrapped and put some tile maps on it. Is there any way to get the tiles on all walls in the same size. I already applied rotation and scale as well as marked the seams and at least unwrapped it.
If you unwrap with “smart” uv unwrap option it will give you much better scale, you will probably have to move the islands a bit individually for them to coincide.
Or you could use box mapping instead of UV.
