We have finished a 16'-16' room in the basement and my son and I are building a 9V train layout. The goal is to build everything 100% out of lego. We have a town section, farm section, industrial section and we would like to create a mountain with a tunnel. I have made a few attempts at modeling the mountain, based primarilry on some of the photos that some of the train LUGs have on thier websites. I have not yet been able to pin down the technique in a fashion that I find acceptable.
Has anyone had any success with this? Anyone have any links to resources that might help?
