Pixel shader problem

Hi,

I'm trying to run the TSE terrain water demo on pixel shader 1.1 and/or 1.4, we need it to be able to run on older video cards.

Right now I'm adding:

$pref::Video::forcedPixVersion = 1.1;
$pref::Video::forcePixVersion = 1;

to:

tse\example\terrain_water_demo\client\prefs.cs

And it works, as in I get a great FPS increase, but the water becomes completely grey, I know it's supposed to now render a cubemap only, so some changes are made to the water rendering, I just need to know is there anything else I need to do?

Keep in mind I'm an artist so please explain any code changes to me like I'm a new-born child :).
