OK i've been fiddling arond and i think i've figured out how to apply Eco Systems to Terrains. i've done as taught and applied the Eco system to the infinite plain and created a plain primitive and applied a different terrain to act as the flooring inside the room. My next qestion is is you can see from the terrain outside and as pointed out it is flat, i little bit TOO flat, i totally agree. How is the best way to correct this? Create another Plain Primitive, and use Terrain Editor to create my own little bumps etc? OR is Vue infinite helpful again by somehow creating the un-eaven bumps that I need? Many Thanks, Philip.
