What I did was to use minitweaker to get SHIV's scene.dat settings & then set SHIII's to the same, this ended up with almost identical to SHIV's water etc without any of their files, no vortex problem, however it also showed up the errors with wave height, "boats appearing to go over land" etc, all we have to do now is extract the relevent settings or even do the reversal to the SHIV's scene.dat (except would still have the vortex problem).
Some snapshots:
Same again with different EnvColors, (still SHIII):
All in All getting somewhere!
