Yeah, the pattern is self-made. Actually with mountains I usually paint them one-by-one, but because this is supposed to simulate an underground fantasy environment, I thought a broad pattern would suffice. So I just painted them one-by-one in a separate file and then defined it as a pattern and then filled this map. Can you see the pattern
too much? As in, is it distracting?
EDIT: I suppose it doesn't matter if it is distracting as it appears now, because there will be tons of those pathways when this is finished, thus cutting through the pattern.
