Does it work in 2.0?

Does it work in the latest gzdoom/zdoom?

Does it work in gzdoom r880?

I tested it in Zan 2.0, only works with OpenGl. Works fine in both ZDoom and GZDoom. I havent tested it in GZD r880.

How about the latest zdoom?

Already said that it works fine.

Sorry that was a mindless copy paste on my part.
Check back tomorrow when I get the gzdoom revision link from Torr so you can see if it happens in the gzdoom base we upgraded to.

Tomorrow, I'll set the ticket to feedback and give you a link

GZDoom 880 is the same as GZDoom 1.5.0. You can test it with this one.

GuardSoul   
2014-06-17 20:53   
Ok, I did the test with that version and it works fine:'http://i.imgur.com/as217Xm.png [^]'

For me it's broken in GZDoom 880 in the software renderer. Your screenshot only shows it in OpenGL. So this is a bug in GZDoom 880. If somebody finds out when it was fixed, I can check whether it's feasible to backport the ZDoom fix.
(0009879)
Edward-san   
2014-07-06 11:40   
Let's see if it's possible to reproduce in these builds:

ZDoom 2.5.0

ZDoom 2.6.0

ZDoom 2.6.1

ZDoom 2.7.0

ZDoom 2.7.1

What makes you think that the skybox change fixes portals?

Please elaborate. First, you point to one changeset, now you are pointing to a bunch of changesets.

From what I understood, the first 3 changesets do not contain the fix, the other 4 changesets contain the fix, the first of the 4 fixed the issue (has the arrow at the right pointing to left).
(0009941)
Torr Samaho   
2014-07-12 13:02   
That is one way to guess what he could have meant. But it doesn't say whether the images where made with a revision exactly before the changeset and exactly at the changeset the arrow is pointing it.

359f21c1aba6a4c0705c5e16fee4c684407e0fb0 is exactly before 4502d7850388839f8036b886147e7e81dc588130 . He avoided doing all the screenshots for all the 7 revisions, so I guess he meant that:

"there's no other change which fixes the problem other than 4502d7850388839f8036b886147e7e81dc588130 ".
(0009943)
Torr Samaho   
2014-07-12 14:15   
That's not what I mean. The important question is whether the two screenies were made with exactly these two changesets. If they were, I also see no reason why he should mention six other changesets.

Anyways, take a look at these Portal bugs. I'm sure they're related to this bug report.


[edit] see this, too.

I bisected and found out that really r2993 began to show up the portal in the example wad ...

[edit] uh ... I can see the same problem in 1.3 in sw, not in opengl. Why was the version set to 2.0?

I believe we can wait for the next code upgrade stage, because there are a lot of revisions which change the portals code...
(0014356)
Edward-san   
2016-02-06 12:29   
I can't reproduce the problem in latest zandronum 3.0 beta anymore. Can someone confirm it?

I'm not sure what bug I'm looking for, but I did notice a weird HOM in software using the example wad.

It also happens in GZ 1.8.6 as well in software.

I can also see the issue in the latest ZDoom 2.9pre-52-g5b74d41 (2016-02-07 16:32:11 +0100)
'https://i.imgur.com/5mzOXPT.png [^]'

'https://github.com/doomtech/zdoom/commit/4502d7850388839f8036b886147e7e81dc588130 [^]'

I wonder why I didn't see it before...
