Summary0001103: Difference in rendering skies between Zandronum and GZdoom/Zdoom
DescriptionI noticed that the skies don't really behave the same way between the ports. For example, check the pictures below.

The first 3 are from GZdoom and as you can see, the texture does not get cut at all and has a nice vanishing point, so to speak. Last two are from Zandronum and as you can see, the sky looks kinda stretched and the sky gets cut off really badly. I mean, I don't even have to look down to see the cutting point whereas in Zdoom (Forgot to supply pictures but I checked and it gets cut off way below, you have to look all the way down) or GZdoom it looks normally.

Now there's something I noticed. The sky texture in question has an offset, I don't know if this should be affecting this or not, but it's a point regardless. Maybe in Zandronum the offsets are somehow ignored on textures? Could also be a renderer issue.

Does Zandronum behave differently compared to GZDoom 323? Also, please upload a minimal example WAD.

It behaves the same as Zandronum. I attached an example wad.

Alright, then it's a GZDoom bug.

This might be a stupid question to ask, but I saw the label "backport later", how late is it? Just asking because this bug really has no way to work around it and my mod suffers from it immensely.

Depends on how much effort is required to backport the stuff.

BTW: can you see which version of gzdoom, downloadable here, starting from version 1.4.0, fixed your problem? This should give an idea on the complexity of the fix.

This already seems to be working properly on 1.4.0. The only minor difference compared to the newer ones seems that the bottom of the cone (I think) is not properly fading, it's being repeated again (the sky texture) then it fades. But it really is no problem and it's already an improvement over the current "stretched" skies. You can use the attached test.pk3 on 2nd post to see this. (I don't know how to attach this to first post after it was made)

Works as intended in v2.0.
