[Question]:Creating caves?

Yah, Since I am still learning how to terrain I was wondering how to create roofs on stuff, Like caves for example? +rep for the one who can help me on this issue

I'm not really an expert in terraining, I started creating my terrains week ago. I think it depends about you camera angle and fog should be darker. Using UTM you can make caves in many ways with walls, or you can do it with big rocks like X.e.r.e.x. did in one of his terrains. Or something like this?

The important thing is that you should use command ''ctrl + PageUp'' or ''ctrl + PageDown'' for raising doodads up and down.

It worked, Thanks a lot +rep
