Why is my landscape painting rigid and "square"?

Yeah, this is what I did. Simply grabbed landscape plane and manually scalled it. Having 1 meter limit is really bad. There should be a way to subdivide areas of terrain that could use more. And if landscape can’t handle any operations like this is should be removed as a feature. As being simple useless with AAA. New system should be made.

I called it a fix as it allowed me to get nice painting in. But agreed that performance wise this might be a overkill. Unless game is small zone based.
