How to Fix Minor Changes and Maximize Visibility
Fixing Minor Brightness Changes
If you have just installed the Full Bright Texture Pack and noticed that the changes seem minor initially, do not worry. This occurs because the brightness isn’t set to the maximum by default when you first load the pack into your game.
To experience the full effect of the enhanced night vision—which brings a quality similar to Java’s maximum brightness—you simply need to tweak the configurations. Open the pack's settings and raise the brightness slider until the darkness is significantly reduced to your liking. Explore the subpack settings to further customize the pack to suit your needs. Enjoy a brighter Minecraft experience across all your worlds and servers without needing any experimental toggles turned on.
