Here is our space. The plan was to have the area as you see. Make a big mountain and then hollow it out. The first problem we encountered was that the terrain in second life is 2D, which means that we were un-able to hollow it out. This wasn’t a major problem, but means that we did have to go back to the drawing board. I think from here that we will build the sides of the enclosure up with terrain and then use a mega prim as the roof.
