[HL25] Software-like underwater effect for opengl

[Comicazelambda]

In software mode the screen would be tinted the color of the water and have a pixelation effect, ofcourse this was also present in Quake beforehand. OpenGL doesn't have this, and in fact doesn't even have the screen tinting.

Here's my video showing off the effect in the map rocket_frenzy.

Here's a video of quake sourceports attempting a more detailed underwater effect

My request is for the team to

• Carry over the tints from software renderer when underwater to opengl
• Create a subtle screen effect for underwater.

Hello @Comicazelambda, this request is already being tracked at #2165. Closing as a duplicate.

[Comicazelambda]

with all due respect this has to do with the underwater effects, unless that and the animated water are treated as one and the same in terms of issues?

[kisak-valve]

Re-checking this and yes, I misread your request the first time around. It makes sense to track water surface effect and submerged effect requests separately.

Thank you !

That's called "Software Rasterizer"

I believe that Half-Life 's Software Renderer looks weird. We would like to improve SDL2 related textures because it is stable for modern Software Rasterizer.
