Been putting a lot of work into grass and forest maps. We started by creating a nice ground texture, then placed tree trunks, then made a transparent "canopy" layer, so people could see both the ground and the tree's hitbox.

I didn't really like it, so we kept brightening it to make it look more like a fantasy forest, and fudged everything. Here's our second attempt : Click image for larger version.

We had a lot of feedback saying the ground needs to be more pronounced, the trees need to be less distracting, etc. So we completely rebuilt the ground texture and double-sided the transparent mask on the tree leaves.

Pretty happy with this last attempt, although the printer printed it too dark and in the phone pic it looks like you cannot see the ground well, in person you can.

And here's some shots of them printed and how they match up. Note that the "transition line" on 1 edge of the forest will be doubled so these transist even better, and you can put those edges on opposite ends to tile giant forests without ever seeing them.
