So, while trying out the Multiverse Beta, I found out about a compatable hight map generating program that could be used (besides the built in one) to create high quality texture map and hiht maps.

While playing around with it, I created this magnificant scene.

And yes, those mountains in the distance are actually part of the terrain, not an image, and can be traversed in game if wanted.

Here the link to the site. http://www.bundysoft.com/L3DT/

Let me repeat, the map files this software create are somewhat realistic and can be used in games.

The free version lets you create high quality, but to go realistic, one must buy the professional version.

edit: after playing around with it, it's a nightmare trying to get the free version inside of multiverse. So much for that.
