Doom Legacy Water Effect - Any Ideas?
Posted: Sun Jan 22, 2017 9:29 am
Doom legacy used to have a really cool water effect. When I say "used to have" I'm talking early, early Legacy from 1999 or therabouts. The effect created almost transparent water, a slight darkening of the light level under the water, an animation on the surface and a cool warping effect of what you could see through the water. I've always really liked the effect and seen nothing quite like it in any other Doom port or mod.
I used to have a video of it on YouTube but it's so old, low-res and compressed that you can hardly see the effect so I just uploaded a new version:
What I'd really like are suggestions on how (or if) such a thing could be achieved in GZDoom. I'm pretty sure that you could get most of the way with a 3D floor and warping textures but, as you can see from the video (I hope), the water creates a visual distortion effect too. Could shaders of some sort be used?
If anyone wants to have a look at it on their own machine, I've zipped up a copy of a suitable version of Doom Legacy and the demo WAD that was distributed to show off the water effect. Much to my surprise, it worked on my Windows 10 64 bit machine so people should be able to run it.

For information, if I recall correctly, the way you did it in an editor was really weird. I think you had to do something odd like give the affected sectors a negative tag of the value that you wanted the depth of the water to be.
