Quaddicted had a 37000 downloads of Abandon. 

I'm working on my first map and suddenly a chunk of my level is not rending textures. This wasn't an issue until now. I don't think it's a vis issue because it happens whether I run vis or not. Any ideas? 

Did you delete the earlier lit file?
Is the wad file in worldspawn updated?
You could check the bsp log file, it says if all textures are in the wad file.

Just guessing. 

Which engine are you using? Also, are the polygons missing entirely, or are they drawn as checkerboards? Or plain white? Does anything visually change as you walk around the level? 

The textures just don't draw at all and I can see through them entirely into the grey void, but only in one specific part of the map. I found that replacing the slime and slimeskip textures in the map fixed the issue, but I couldn't find which brush specifically was causing the problem. I ended up removing all the slime brushes and will recreate them. The weird part is I made no changes to the slime brushes or textures before this started happening, so I'm curious as to why it suddenly started. In any case, I found what was causing the issue and hope it won't happen again when I add the slime brushes back to the map. 

Hello again. I am once again asking for some leak help on my map. Even though I have both the tooltips and rj's grid suggestions (see posts 20903 - 20908), my map is leaking in a new spot, and I cannot figure out why. I've manually forced every vertex on any "see-through" brush and its neighbors countless times, but the leak persists.

Once again, everything that could be needed (.qrk, .map, etc.) can be downloaded here: https://ufile.io/g6ivjqeh

I won't be surprised if this is just me being blind, but I don't think it is.

You made the secret entrence a bit complicated.
I used the QuakeLab exploding_wall to simplify it.
Maybe not the best solution, but it works.
Realy take care with lightning. Not smart to use delay 2 on small places with such amount of light, they'll get overlightened.
This because the last part is such a dimm place.

Keep mapping!
You're on the right track. 

I wonder if it's a problem with QBSP handling skip textures -- the missing polygons behavior is what would happen if they had a skip texture on them, maybe it's a compiler bug? If you run into it again you could try a different QBSP or see if there's a command line option to disable skip removal, and see if either of those things makes the problem go away. 

Thank you so much! Is there anywhere I can find an archive of more QuakeLab stuff? I tried going to the website in the text file, but it seems to be long gone. Any functioning crawl on the Wayback Machine just points to in2net's 404 screen and the crawl database for the site is full of unreachable 4XX errors. 

I made the mod Abandon, based on each map of the QuakeLab.
And yes.., that's all gone because of these files were archived from the Bill Board Service from 1998.
I placed them on Quaketastic and you can find them here:

Happy mapping. 

I would like to let players and projectiles or bullet patterns ignore certain faces with the waterfall texture applied to them. Is there a cool trick to do this sort of thing in trenchbroom? 

func_illusionary 

that's the ticket. 

I am having a similar problem and have had no success either. Any update? 

whenever i try to use vis.exe on my .bsp, it says "LoadPortals: couldn't read map_name.prt". It was running just fine a second ago, so what happened? 

or your directory is changed with the last qbsp compiling.
Compile again and see if there are no leaks. 

I'm working on a project where I need to add some coop starts to a BSP that doesn't have them. I've been able to add other items no problem, but coop and dm starts give me a player model precache error.

Using this tool to insert the spawn points:
https://jpiolho.github.io/QEBSPEditor/

And the mod is progs_dump 3. But I'm sure we didn't change anything re: precaching of player models.

Testing in IW 0.7.0

I'll keep testing an perhaps try some other tools, but wondering if anyone had any ideas why this is happening. 

To be clear, I don't have the map source. 

I tried adding a trigger_teleport and destination using a bmodel hack and crashed with the same error. After successfully trying AdQuEdit it looks like this is an issue in the web tool linked above. 

Nope not the web tool. Copy and pasting entities from TrenchBroom was causing issues. I was using TB as a reference for the ents and occasionally pasting causes issues. Probably re-ordering entities in some way.

SOLVED 

Yay! 

Jo! 

I have a separate project where I am trying to export a 2D view of my map without any distortion from the orthographic view. The top down 2D viewport view would be perfect for my needs but I am unable to find a way to display textures. Does anyone know of a solution for this. Even a different map viewer would work If it had 2D views. (the only messy solution I have found so far is to screenshot the 2D view and add textures later.) 

Im new to modding and I want to make a gate door swing open on a trigger.

I have already made a mover entity rotate on a trigger, but the pivot point is in the center of the brush. How can I change the pivot point? or what would be a better way to do this ?
