The coolest part about this mod is the light seems to come from the world’s objects rather than the sky itself – it’s very interesting to see for the first time. Basically this is an advanced tool for adjusting brightness, gamma and other aspects of lighting in Minecraft, which allows for the brightness slider in the options menu to be overhauled and taken well beyond its standard maximum level.
For players who just aren’t getting the kind of brightness they want from Minecraft, which is a surprising number, the Gammabright mod is just the thing to help make Minecraft easier to see during the darker times in game.
