User blog:Stormzone5/Which world is the Middle-earth?

I downloaded a texture that changes the lighting of the game called: Vannila lighting overhaul.

It uses Optfine / Mcpatcher to work, in the Mcpatcher folder there are several light layer images written under World 0, 1 and -1



It works as a shader, but it does not work on Middle-earth, how do I make it work in this dimension?
