Thanks for the response Sivan!

Before I even posted this I had stumbled across your page and was admiring your Map Builder. It's pretty impressive so far, well done.
Also, thanks for the tip on L3DT. I've heard of it just never looked into it, but I'm going to now.

Speaking of your map builder though, I don't even know if it's possible, but do you plan to add a terrain generator at some point in the future?
