First off in your UTEngine.ini there's a [SystemSettings] section.  In there you will find this setting:

[size=18:9626d4d49d]FloatingPointRenderTargets[/size:9626d4d49d]

If you set this to False you can see through water, slow fields, x-ray fields, energy shields, and it can be used as an alternative to FogVolumes=False in 2.0 (i.e. no sand in Sandstorm).  Portals are also RenderTargets (because it shows textures from another location) so it will effect portals as well.

Notice that their's no water in TrainCrossing.

No water in Necro.  There's also a slow field and energy shield on both sides.
