In the Example Worlds there is one called Floating Islands, which shows how to use the Depth Mask to create a floating island. Kind of self explanatory, but today I found myself wondering how you are supposed to texture it. I can conceive of how the texture could be created for the bottom half, but how is it applied to the mesh? I assume it’s a UV mapping problem, but I don’t know if a UV is created for the depth mesh. Is this something you have to take into a third-party application just to handle that part?
Curiosity is killing me…
Note: This trick does not seem to be possible using Meshify and its Force Full Resolution (Water) port. You’d pretty much have to create the two halves of a floating island separately and combine them in Blender, or something. Not impossible, but at least doing it that way means you can get optimized meshes to work with.
