WARNING: Flipped triangle ... How to fix this?

In my
bsp compile (q3map2) for
AEcantw2 I get this warning:
Code: Select all
--- MergeMetaTriangles ---
0...1...2...3...4...5...6...
WARNING: Flipped triangle: ( 996 624 -30) ( 976 624 0) ( 1040 624 -96)
WARNING: Flipped triangle: ( 996 400 -30) ( 976 400 0) ( 1040 400 -96)
7...8...9... (0)
The obvious path: Open the
.map source file in a programmer's editor, search for the coordinates, take note of the brush number, then search for that brush number in GTKradiant, delete it, to then recreate it... alas, does not work. Because those coordinates for some reason are not in the
.map file.
Any suggestions?

Is it actually visible within the game? I'd ignore it if it isn't.

in this post Dragonne talks about it, not sure if it might be any use.

@Silicone_Milk
I have not noticed it, yet. But that may only mean I have not been looking closely enough.
@Delirium
Alas that link is about terrain. Though it does hint that massive amounts of not properly caulked brushwork (here terrain), may cause such an issue. I have been "relatively" on the ball concerning caulking, though.

Just delete the brush in the .map file, you don't need to look it up into radiant...

As I pointed out the coordinates do *not* occur in the map file. So I cannot locate the appropriate brush and delete it.

Sorry, I thought you were looking for the brush number within radiant.

Make a new level and copy paste over the old level? That has solved similar errors for me when I have had brushes that for some reason didn't exist but actually did existed...

You have a surface where two or more tris (triangles) share the exact same coordinates. It doesn't really matter, though. q3map2 simply filters out the duplicates.

Hmm... my changes to the geometry in the map, adding new areas, I almost completely deleted one sector seems to have removed the issue... whee... I think.

IIRC, it may also have to do with certain brushes with many many faces.
Not unlike this guy:

I was a tad slow to "get it". I could have located the location in GTKradiant, using those conflicting coordinates, to delete the brushes there. Still strange that the exact coordinates (i.e. vertices) are not in the map file, q3map2 may be referring to a plane instead.

Yeah, they're coordinates on the same surface (as in brush face). The warning occurs during the meta phase, when surfaces are merged, so if you have any intersecting brushes, that might well be the cause.
