After various cases of "Is it this one? Delete, recompile, No!" etc I just deleted the whole lot and started again.

Good news: No leaks
Bad news: wtf...

(could have sworn i was in the screenshots directory, oops...) 

Yep, thats a missing face, check for floating point inaccuracies.

Or even duplicate brushes at that spot. Or or or.

Try to keep the brushes on grid and their texture alignments too. 

Snap the verticies of all nearby brushes. I think it's under edit? Or Tools maybe. 

Okay, figured something out. No matter what the brush looks like, as soon as I add it inside this area, that wall to the in the WTF screenshot gets the missing face. Even these 2 pillars I have in now cause the same issue.

Just ran a test. Compiling the exact same .map with txqbsp instead of tyr's and that brush works fine. 

In my experience those sort of differences between tyrutils and txqbsp are usually due to the different default epsilon values the compilers have.

For research purposes: try passing the flag "-epsilon 0.0001" to txqbsp, it should bring back the flickering face. The next version of my tyrutils-ericw will support that "-epsilon" flag so you can tweak it.

However, as ijed says there are probably some off-grid brushes / small misalignments that are the root cause. 

Just gave it a go but no flickering faces that I can find anywhere. Tried snapping vertices too (Ctrl+A and the ctrl removing all the entities. Ouch)

Thanks all though. Giving up for today. I'll make do with the misaligned trim for now. 

I don't really wanna do any wall detailing. but here's some screenshots before the final release:

thanks for the advice on the lighting tools and everyone elses input.

looks good. I can see some vertex snapping issues in that screenshot on the right hand side. This type of architecture can be difficult to get on grid for sure. 

It's actually on grid in editor but it turns out that way after qbsp. Don't know how to deal with it. 

pulsar: which editor and compiler are you using? make sure you turn off integer planes in TB, this has always been the source of problems for me. 

and same goes for radiant, there is a integer option there as well. 

tho I've got an idea of how to fix this. Though every vertex of these brushes is on grid I have a problem with the shape due to the difference between rear face that can't be seen and face that is actually visible. If I cut of the rear part of each brush , I may solve this problem.

I used to get issues like that when I used Worldcraft. 

for something like this it may be better to use pyramid/wedge shaped brushes instead of cuboids. 

vertex being on grid has nothing to do with it.
the plane described by those vertices cannot be represented by an integer, this is the source of the problem.

try using other shapes like fifth is suggesting, also try splitting that square shape into 2 tri faces. (eg: turn 1 brush into 2 brushes each representing half the face). 

necros: I use jackhammer and updated version of aguire's txqbsp.

fifth: Yep, that was the idea I got. I'll try it when I get home.

It's funny that such ideas come not when you're making the actual part, but when you share it. 

paper dog programming! 

Making curvy corridors are always difficult. I tried once but gave up after some time, so well: you made it right, keep it up ! 

Worldcraft/Hammer for some reason lets you use vertex editing to create bullshit impossible brushes that you only notice when your bsp is full of cracks. Primary reason I stopped using Hammer tbh. 

To make curvy things in Quake, it's best to stick with triangles (triangular pyramids in this case).
