Something interesting.I was checking different odf classlabless from this link:

https://sites.google.com/site/swbf2modt ... /odf_guide

and i found that there is a odf classlable "water".
I tryed this on my prop model.
I switched the classlable from prop to water however the game simply crashed...i wonder what the developers were planing with this...

Some other interesting trick i was experimenting with.I added a water to my map.On top of the water i added a little flat platform with 50% transparency.So since the water i just beneat the surface of the platform,my platform look just like it have planar reflection effect (which is coming from the water).It looks really cool however the water is moving up and down slowly which ruines the effect.

Can someone tell me how to stop the water from moving up and down?

I only see one ODF with the water ClassLabel here:
assets\worlds\YAV\odf\yav_water.odf
but it references a nonexistent msh file:
yav_water.msh

Can someone tell me how to stop the water from moving up and down?

According to a thread on secretsociety, you need to adjust the Oscillation setting:

fel1.fx has this:
OscillationEnable(0);

Yes i found that today while i was experimenting.

Still im curious for what is used the water classlabel?
We may never understand that...
