Naturally Lit

This datapack reduces the maximum light level for hostile mobs to spawn in the Overworld from 7 to 2, heavily reducing the amount of "torch spam" you might need to prevent mobs spawning.

This means torches up to 25 blocks apart before hostile mobs start spawning, compared to vanilla's 11.

This datapack will likely be incompatible with mods or datapacks that change the maximum / minimum world height of the Overworld, as they and this datapack will likely modify the same file.
