I'm sure you've heard it a thousand times already, but congratulations on your map being accepted!
Here's a few minor visual things I noticed
You can see a tiny bit of light leaking through from the backsides of these displacements by the last point
Coords: -1315 1747 -195
Can be seen from in bounds too ^
While we're still over here, if you rocket jump while against the left wall you can see a tiny bit of a hole in the world where the displacement ends where the road curving up and the ground to its left meet. (slightly up and to the right of my crosshair)
This barrel up by the last point has some kinda weird vertex lighting. I unfortunately forgot to get a picture but there's a similar issue in one of the barrels near C (i think by the path leading from the flank route that comes in from outside? the area with the max health kit)
Coords: -3694 1291 343
The lighting on this wall near B is kinda blocky? its not super noticeable due to the sun spread settings
Coords: 700 -380 324
You can see this seam near blu spawn where 2 displacements with different textures meet
Coords: 4853 1274 4
This wall near C uses a horizontal wood texture instead of a vertical one like the rest of the building
Coords: -2135 -1090 0
These last ones mostly make sense for optimization reasons but there's a few things i'd change, plus some weird oddities.
you can also see some nodraw from the top of these support areas, but its high enough that its not a big deal, and hard to see unless you intentionally launch yourself into the skybox with a few stickies
Coords: -3435 1008 832
same location, but turned the other direction, for these ones you only need a rocket jump from one of the roofs at last, and you can get a pretty good view of some more nodraw. The cliffs make sense, but the bridge with the dump truck on it can even be seen by classes like scout, if they jump towards it.
Additionally, you might notice some other weird things in this image, like a flat plane through the hole by the dump truck. For some reason i can't possibly figure out, that one displacement from the little rest area at the first point is rendered. Its not in the PVS, I've been trying to figure this out for a solid 15 minutes but it doesn't make any sense.
There's also 2 lines rendering through the 3d skybox in this image (over one of the trees to the right of the middle of the screen), which as it turns out are the rails from the building by C.
You can also see 2 displacements from the cave area next to it, but its a bit harder due to backface culling and the cliffs in the way. If you go high enough they'll render through the 3d skybox tho. Same thing as above, i don't get it, especially because NOTHING else from this side of the map renders. I even went over there after locking the PVS (r_lockpvs 1 from one of the roofs at last in my case) and depending on the angle i was looking at sometimes the displacements would stop rendering????
Speaking of those rails at C, if you go high enough (its very high) at the corner before entering the building with C, you'll see this area, with a rail just stopping before going into the other train, and then next to that, another rail (same texture on the same brush) just going through the building and doing the same thing. Plus a good bit of nodraw, there's a tiny bit at the end of the main rail because the rail is a bit lower than the wood brush around it, and it looks like the water towers have no tops as well? Once again so high up that you can probably just skip this one tbh
Coords: -2204 -1151 1134
Hope this helps!
