I've got a question about the trees. In post 35 I mentioned the difficulty I encountered with individual trees. I followed Tonnichiwa's advice and went on the internet to search for a method to do so and came back empty handed.

Here's my problem :

Using a brush I have an overlapping problem, I'm forced to copy and paste the same tree (30 000 + times on the last map and one more is coming ...).

Can someone help me ? I've seen many maps with many trees without overlap, there has to be a solution, a tutorial somewhere.
