I have a question about the best way to place repetitive elements on a map when using Photoshop, such as trees or mountains. I'm aware that this can be done using the Brush Mixer, which is what I've been attempting to do. Painting with it is fine, or just placing individual trees here and there with some size and/or angle jitter, etc. I tend to just click and place a single tree and then do them over an area this way using variant trees, although I do paint with the brush over larger areas for a "base". My issue, however, is that when I click to place a tree, any subsequent tree is placed beneath the previous one(s). Is there any way to change that, to vary the layering/z-index with each click?
