my world is completely black except for the sky, water, and ice. light blocks like torches have no effect. I am using the default settings at low and have no other shaders except optifine. is there any fix to make the world visable?

Same

Sorry for the late reply, but this is not something I've seen happen before with Arc so I'm not even sure where to start. Can you provide a screenshot with the debug menu pulled up? [F3]
