XNA 3D Terrain/Environment Engine
I have been attempting to make the basis for a game idea that I have had. This basis is an environment for the game to take place in, terrain, vegetation, all that jazz.
Unfortunately, I am not the best at this sort of thing, and I am getting bogged down in it rather than actually working on gameplay.
I have done quite a lot of searching, and haven't found many Engines that I could use to work from, and those that I did find were outdated or obsolete now.

So, does anyone know of any XNA 3D Terrain/Environment Engines that are free to use?

Any help would be greatly appreciated!

Thanks in advance!
