Z-fighting?

[Lukin]

Take a ckoser look at this shot:


It looks like a z-fighting bug, but there is no duplicated brush over there (you can check the map for yourself, it's visible on the wall behind the broken red neon).
Any ideas how to clear this?

I don't know about The Doom engine, but if you can, try to use a Z-Buffer of 24bits or more. zFighting dosen't need to be connected to faces overlapping, it can be when the zBuffer is renderd with low quality. Could be a driver error also...

I have a few like that in my map right now, it went away after I deleted the brush and remade it...

If nothing's overlapping, check your nearby light volumes... odds are there's a light center that's positioned planar to that face - that can cause the shadow tris to z-fight with the geometry.

It was indeed "light center's fault". Thanks.

Lukin next time you'll want to take a screenie with g_showhud 0 (and ui_showweapon 0).

Ok, I was in a hurry when posting it.
