Dynamic Fullbright

Traditional fullbright mods apply a nightvision filter or set the light levels all to the maximum. Dynamic Fullbright instead offers the ability to clamp or scale light levels, retaining the lighting ambience of the area while still making things visible.
You can set everything to the maximum to achieve true full brightness, or tone it down to suit your preference.

Example

Dynamic Fullbright works by taking the lightlevels obtained by the render thread and shifting them during lighting updates.

The default settings scale block and sky light levels to be in the range of 4-15.

Extras

With cloth config and mod menu, you access the settings to bring the brightness to anything you desire.
