I'm GM'ing a game in the Humblewood 5e setting, which features a lot of houses built into parts of trees, either within their hollows for the very large ones or as what we would think of as treehouses more akin to Robinson Crusoe. Since the default tree houses included with CD3 look a bit too neon for my tastes, I'm trying to figure out a way to make treehouses. I'm messing around with multiple vegetation layers and the Celtic Bitmap A style houses, but have yet to figure out how to make it work. Any ideas or examples of someone doing this themselves? Thanks!
