I can't find documentation for this. I needed to change some landscape stuff to make a cave entrance, but I have one big question/problem. How do I remove grass?

Grass is randomly generated based on the landscape texture. To remove it, paint over it with a NoGrass texture.

If the grass stays there, then it's just a CK display bug. It won't stay there in game.

Alright, Cool. Thanks for the info
