does anyone know how to make a UV float around (translate rotate,2 sided) inside an object? sort of like a glass marble, but if the wavy things inside were flat? but in local space so the marble can still roll?
or is it cheaper to just make a render target with a 2nd camera of what would be inside and use that image on a screenspace UV on a sphere? but then that would be harder to figure out where the camera would point if the marble rolled.
