Adjustable Fullbright

How it works:
The modpack modifies the vanilla core shader lightmap.fsh to increase overall brightness (compatible with Sodium).

Lighting is first computed as in vanilla. The final lighting color is then blended with white by x%, as controlled by the vanilla brightness slider.

Advantages over alternatives that push the brightness slider beyond 100%:
Light gradients remain much smoother and less saturated.

Vanilla at 100% brightness :

Adjustable Fullbright at 33% brightness :

Adjustable Fullbright at 66% brightness :

At 100% brightness, it’s just fullbright with no light variation at all !

The pack also totally disable night vision at brightness value >= 25% and have a very reduced effect at brightness < 25%.

Before the fullbright is applied, The vanilla lightning brightness is calculated with a brightness between 50% (when the slider is at 0) and 100% (when it’s at 100).

The changes are minor and easy to understand, so feel free to modify the shader directly in the pack to suit your preferences
