Thats pretty neat. I tried Blender some years back and found the user interface hard work. But I am told that it was accepted by the devs that it was lacking and completely re-engineered and is now much superior to how it used to be. One day I will have another go at it. Without question it is a very powerful app and can do amazing things and it just takes a lot of learning. Have a browse through some of the maps by the member Falconius who has supplied some wonderful examples over the years.
