Is there anyway to make the area around under ground paths and coasters textured instead of all black? I've used the exposed underground surfaces brush and nothing happens, even to the edges of raised ground. But when I put those square ground blocks on an area that I just painted, they have the same texture, and I can sink them into the ground around the path, but that's sooo time consuming. Is there any way to make my underground paths tunnels instead of just going into a black abyss.

Well, you could place lamps on the pathways not sure if i understand what you mean, but i hope this helped...

Sadly not but you can just make the underground a trench and if you have soaked you can but those ground covers on tho cover the trench up and then color the walls.
