How do you Add Cave Walls?
Certain map styles have walls when you draw a cave and others do not. While I can click the wall tool and draw a wall around it, it won't really match the fractal pattern of the cave. Is there a way to add a wall when drawing a cave if the style does not have it by default?
Related to this, if the style does draw cave walls, is there a way to alter the thickness of the wall? I click on top and try a different width, but it does not seem to alter anything.
