Hello, I want to make an area that maybe has 4 terrain patches in it, that is unseen from Oblivion or SE that has its own world space. How is that accomplished? The terrain tutorial talks about replacing an existing patch in an existing location. Do you just clone an existing world space? I didn't see a "create new space" option anywhere.

It works like creating a new cell. Go to world>world spaces, right click somewhere in the list and select new.
