I noticed with the mod installed my water got quite a bit brighter. The block shading/AO looks pretty flat as well. Is this something I can toggle off, or is it a bug? I have comparisons of vanilla and ArchaicFix with Phospher toggled on and off.
Comparisons:
(Vanilla)

(ArchaicFix, Phospher toggled off)
