What in the almighty flimflam is this? (GZDoom graphics problem)

[Caru]

So first question: is there a convenient way to export a small part of a WAD (i.e. a single map and optionally any assets that happen to be used in that map) so I can quickly ask for help with a problem without having to upload the entire WAD? Because I don't know how you'll be able to solve this problem without actually being able to look at the map itself, but being as new as I am, I'm still super uncertain about what is an acceptable form of sharing things, and what would be considered an intellectual property faux pas.

 

The second, more relevant question: the hell is going on in this screenshot? This one, vaguely triangle-shaped sector seems to be behaving as though it's missing a texture, but I have checked over and over and there are no missing textures anywhere in this room. As far as I can tell, this sector doesn't have any settings (other than a slightly different ceiling height) that are any different from its neighboring sectors. I am using GZDoom and, critically, this only appears to be happening with hardware-accelerated rendering; software rendering appears just fine. Does this by any chance set off alarm bells for anyone just from the description and/or screenshot, or should I figure out the answer to Question 1 first and let you guys poke around?

 

Edit: The hell with it, actual missing textures or not, most of the main area is using default textures anyway and it looks like I can comfortably put just the map in a WAD file and more or less communicate the problem. So I've done that and attached it to the post. The map is in UDMF format. PEMap Debug.zip

Question 1 - You can use SLADE to export the lumps you want into another WAD file. About intellectual property stuff, I'm not an expert, but I guess it would be acceptable if you clearly state that the map isn't yours.

 

Question 2 - This look a lot like a sector-not-closed bug. It means that the sector you have is not properly drawn and therefore is not rendered correctly (either there are overlapping linedefs or a wrong copy-paste stuff happened). To solve this, use your map editor's "map analysis" tool. Default key is F4 I believe. THen you will be able to delete and redraw the sector properly (properties are normally conserved when doing that).

Sorry if I'm being unclear. Don't hesitate to ask anything else if that didn't work. Normally it should, but you never know.

1. Exactly what I ended up doing. xD The map is mine in this case, I was more concerned about textures, custom monsters, etc. But good to know!

 

2. This worked perfectly. Looks like the sector's vertices were unaligned with the grid; luckily the map analysis tool had a handy "align vertex" button for exactly this purpose, and that appears to have solved the problem. Thanks for the rapid response!
