Rotatable fluids work fine if water blocks are next to them but lets say the carpenters blocks is completely submerged like this: http://puu.sh/l0GA0.jpg the water texture above is still active.

Also if you have a something setup like this: http://puu.sh/l0H7K.jpg Then the water texture is still shown even though the empty side of the half block is facing air.

I do know this feature is not intended because if you have it facing water above without any water on the sides: http://puu.sh/l0Hj9.jpg You dont see the water texture unlike vanilla glass: http://puu.sh/l0Hm9.jpg.

I would like to see this feature fixed for submerged carpenter blocks because atm this is the only mod that can allow you to see the outside ocean though glass, without the dumb water texture infront of it.

Known bug. I will have a fix out as soon as I can.

That would be great if a fix could be out soon. No pressure but a modpack is waiting for this bug to be fixed before it releases :)

Development build 3.3.8 R3 includes this fix.
