Pretty clear water (or water volumes)

I was wondering water volumes like this can be implemented in Gzdoom since the port already has water volumes. I'm just wondering about the liquid look.

Something like that, but I'm not asking for a polygonal bumpy water, just something more realistic than the doom water textures.

Sorry, but there are several problems with it:

1. It doesn't fit into Doom
2. My experience with advanced 3D-programming is close to zero
3. I really don't have the time.

maybe at least clear water that looks like the "shader map" the mirror produces?

The old DOS legacy used to do a transparent water trick that didn't look too bad at all. I remember the editing method for it was clumsy (I think it was something odd like you gave the appropriate sector a -ve tag to the value of the water depth). I think it also made use of a special flat in legacy.wad (or whatever the legacy resource wad is called). I don't know if the feature still exists in legacy but it certainly did. It was an old software trick, so I'm guessing advanced 3D programming wouldn't be needed for it.

It was a software trick indeed. And it was pure crap in terms of implementation.

When I looked at the screenshot I tought

OMG GZDOOM!

But then I read the replies and it was disapoinment

this is transparent water with cubemap environment map, however you can do at least spheere ( yuck! ) mapped environment map using same code as on mirrors
However both will probably need to render environment to their textures and so...
So there is really not much that can be done with it

Maybe zdoomgl will have it diffirent as timmie was last time messing with fragment programs and such who knows?

Just out of curiosity: Do reflexing floors and ceilings work with software mode?

No. They are simply ignored so even if you want to stay compatible you can use them without risk. Just don't rely on their reflections.
