Playing around with vert paint, decals and blend meshes. The sand hasn't been touched yet, going to try to get some water in before I quit for the night. The vert paint is totally temp, I'm planning on making a new asset for the bottom of the tree and root system.
Some grass and plants for the floor of the oasis. Most of the adjustments will be when I get all this into the scene. Also I just threw it together pretty quickly, plan to do a much nicer job laying the planes out.
