I've run into a major problem. I'm using the latest version of the Extreme Vibrant shader on a Minecraft v1.12.2 modpack,FTB Revelations to be specific,night is visibly identical to day. I do not have any nightvision effects active. Night on the surface is just as visibly bright as it is in the day,while the game recognizes it's dark,so it starts spawning mobs. Indoors and/or underground,lighting is fine. What do I need to do in order to fix this?
