all my searches came up as "you cant modify vanilla water"... but I knew it was all lies!
barely tested beta version, might be broken in areas, has some odd square looking spots at some times of day, designed to work with the 1.12 improved models which is named patch-3.mpq, so I named this patch-4.mpq, extract from Data folder to Data folder in WoW directory to install, or install the whole reshade to main WoW folder
the shader on this water much more bland and whispy than the official Cataclysm release but removes all the repetition of textures that vanilla textures have
includes a reshade for a replicated newer wow feel with focus on added water variation
