The problem i'm trying to address has more to be with creating tools for
production than rendering. For rendering, I think the approach i'm using is
the same one Unreal does, just streaming higher mipmap levels for objects
that are closer. For megatexturing, I think the biggest advantage of it is
the fact artists have a tool that allows them to paint directly over
everything, and not so much the fact that of using a texture indirection. I
guess the added advantage is that they can bake lighting extremely well.
