I wonder if the animated chunk loader or maybe Astral Sorcery would be messing with the sky somehow, but it's a wild guess at best.Two questions:
What mod might be the culprit in Sprout or Openblocks that's not in Beyond that would break my ability to use custom skies? The Custom Skies option is set to on, before someone thinks I missed the obvious.
And, I don't have any hope here, but does anyone know if there's a fix for using inverted sky blocks with shaders? Breaks everything I've got as soon as they would be on screen.
When it comes to shaders, I've got nothing. Sorry man.
