I have a problem when using Optifine (all versions). When I am outside, all looks right: the daytime looks bright and night black. However, underground is a different story. Even without torches, caves look bright as day. I have adjusted anything and everything that would seem to affect lighting: Smooth Lighting, Smooth Lighting Level, Brightness, and Dynamic Lights but nothing seem to affect the lighting. Any ideas? I want caves to look dark like they should.
