Dr.Splat's Transparent Water Hack for Non-GL Versions of Quake and QuakeWorld This utility will allow people to see things in the water and people in the water to see things outside of it with the non-GL versions QuakeWorld or NormalQuake. You can see into the water, but you won't be able to see the waterline.
There will be no water texture at all, so it will look like the water is just a normal area of the level (except if you are in the water, then you will have the same warping, water sounds, and palette change, but you will still be able to see everything outside of it).
