Overgrowth WOES

[{HHx}b14ze]

Well, when i tweak around with the density to about 300, the trees/bushes appeared. I could not however, paint more on, take some off etc. Im not sure what im doing wrong. Why am i selecting a color (blue) for the over growth when it is showing up in the editor as normal color. In the undergrowth i selected green and the grass shows up as green kind of like in 3d. Someone help as the overgrowth is the last part i need to finish my maps! Thanks.

Ok new development. When i click render/overgrowth mode, i can see the color that i chose to paint the overgrowth. Problem is that the terrain is all black and i cant tell where mountains start and grass ends etc. Any ideas peoples?
