Does the object population procedure have some sort of "collision detection"? What I mean is, if I'm populating more than one type of tree, does the procedure know not to put two different trees right on top of each other? Or if one object was a log cabin, would it know not to plant a tree out the roof of the cabin?
I know collision is the wrong word, since these things aren't in motion. I couldn't think of what to call it though. I hope you get what I mean.
