Automatic Forester

[Fluesopp]

So for a forest, you only have two layers, right? One for the trees and one for the shadows?
What I'm aiming to do, to resolve that, is to draw the outline of a tree, without anything behind. And for the tree underneath, I draw the mask, only instead of drawing in a color, everything it draws should become transparent. This solves the problem with trunks overlapping a tree below. (The problem with trees coming on top of another tree is because of I draw them when they are assigned. It will be changed, but it's a different
problem.)

And what's the clone stamp technique?

Yes, for the forests I did on my first two maps I only had two main layers, trees and shadows.
My new map has three.

The clone stamp technique is explained here...

but it is basically what you are doing anyway, with the white behind a brush to mask off previous trees. It's nice but one problem is you have to the tree layer on multiply, or mess around with the magic wand to delete the white - something which doesn't really work if you have shading on the brush.
