Shader compatibility
This pack was tested on two shaders: BSL* and Complementary. They both work fine, except that the fog color doesn't change (so if you go to a mesa the fog wouldn't be orange). If you are using shaders other than these two, then it may or may not work.
*If you turn "Vanilla Sky" to ON
