Summary0002515: Strange Skybox behavior online with multiple skyboxes. (Only on some maps it seems)
DescriptionAttached is a test map that gets the issue. The skybox in the map looks like this online:'http://puu.sh/lcoMN/8c876546b7.jpg [^]'

When it should look like this:'http://puu.sh/lcoOz/5406c9c967.jpg [^]'

I tried making a test map with multiple skyboxes with different tags, but I couldn't reproduce it that way. So I replaced all the textures in the attached map to make it standalone. Ignore the unknown thing errors, I didn't want to change too much lest I stop being able to reproduce the error. Thankfully it still reproduces the error.

It's worth noting, this bug does not occur in 2.0. Nor does it occur in GZDoom 1.8.6, this is a Zandronum 3.0-only bug.
Steps To ReproduceHost a server with the attached map, join it. Compare it against the screenshots I posted in the description.

 Can you condense this to a minimal example wad? The smaller the better. At least the console shouldn't be flooded with errors.

 I cannot. I already tried, three times.

 Please elaborate. What's stopping you? Does the error go away if you reduce the size of the map?

 I tried reproducing the same environment in a test map, but it didn't produce the expected result. Some combination of conditions that I cannot narrow down results in this bug.

 Did you try removing things and sectors from the existing map to make it smaller?

 i have attached a minimal example wad (couple rooms taken and modified from striker's map) that can reproduce the issue online and behaves normally offline

it seems that its caused by the fix for this ticket:'http://zandronum.com/tracker/view.php?id=2350 [^]'

excerpt from irc:
<Torr_Samaho> If it really only happens on huge maps, it could be a problem similar to'https://zandronum.com/tracker/view.php?id=2520 [^]'
<WaTaKiD> actually, i was tinkering with that idea, i was removing stuff and making the map smaller and whatnot, along with using the latest changeset, no change in the sky
<WaTaKiD> however, i just tried a build from before ticket 2350's fix, and the sky appears as it should
<WaTaKiD> then i tried a build just after that fix, and the sky is doing its issue

 Thanks, that kind of example map was exactly what I was looking for!

 using'https://www.dropbox.com/s/obffhny5vh06g6e/zandronum-3.0-r150809-0703-83ceae7-windows.zip?dl=0 [^]'

and ticket2515.wad, it seems the issue is fixed

also just in case, i tested portaltest.wad from ticket 2350, and that issue remains resolved

 Both worked for me as as well with the above build.
