Finally! I painted the materials on to the first section of cave.
The Material blends five groups of color, normal, and roughness maps using vertex RGB, Alpha, and 1 - Alpha. The blend transition is further assisted using a blend map and HeightLerp.
I'm pretty satisfied with the results. Now that this is complete putting multiple sections together should be a breeze.
Below you can see a result of the blending. All the materials and modeling, as usual, are completely original, running real time in unreal at steady 120fps.
Now for some fun models! My plan is to create crystals, mushrooms, roots, and maybe some small rocks. I'm not too excited about the rocks, since it is so boring, but it'll probably be needed.
