This happens to me everytime I have a brush with many / small surfaces...
Anyone know how to get around or fix this?

Some trim in a CTF map I'm working on...
It's an extruded 6-vertex shape, rotated around an both an inner and an outer axis (does this make sense?)
I've found out btw that this problem de-exists if I use a light source with a radius ~= 64. In the lit pic above it's a 255 radius light. Hmm, suppose this is an engine problem... some loss of precision when raytracing far rays?

Do you mean the strange black stripes? Sometimes things just light weirdly depending on how the polygons have been split within the BSP tree. You can sometimes make this go away by changing your polys to semi-solid or just adding or removing brushes in the problem area.
No, it doesn't. As I said, it's only concerning big radius lights - not light sources that are close to the brush. (I mean realtively close)
I've tried:
- Bright Corners
- All sorts of Shadow Detail
- Setting the light to LE_NonIncidence
- Rebuilding
- Rebuilding again
- Performing a poly merge on the brush (not that I had hoped it would help...)
- um... Think that's it.

i guess you could try setting all the faces on that brush to special lit and putting some special lit lights close enough to light it, it might stand out against the darkness of the wall if you make them too bright though.
yeah, that sure works, as I said: the problem exist only with light from far off (light radius < 64). I worked around it (making the whole scene night-ish 
but still it would be good to have a way to get around this...
I bet in U2 it's fixed

I know...
I've tried that first, in fact - it didn't help. It just made the contrast clearer. Those few faces are *pitch black*!

a similar problem can be seen if you subtract a brush from a room, those faces are not light (at all, they stay black) from the light in the room, even when they clearly should.
doesnt matter if you set it to 255 bright, nonincidence, cylinder, chnage the radius. zip. nothing helps. that face stays black. even when you make the light special lighting and the same to the face, nothing. Sticking the light in the brush doesnt help either. hmmm. maybe UED doesnt like small subtracts or something

Um... tried setting the face to "Bright Corners"? That usually does it for me with those small faces... Tried that on my brush as well, just didn't help.
it's a problem with the lightmap resolution, there's no real 'fix' for it until U2 comes out.
great innit.

I've had this problem on shapes that were processed a lot. Somewhere during all this subrtraction, addition, intersection etc.. one or two faces seem to flip around showing their backside. The only fix I've found is to always use geometry with two sided faces if You suspect this would happen. And that includes the original, so to say atomic brushes. Especially the intersection seems to suffer this problem big time. Using two sided faces all the way along is propably not a good idea... although I suspect the "compiler" will optimize these away.
Light:
Sharp corner!
LE _ Nonlncidence
Special Lit
Texture:
BrightCorners
Special Lit
The change of a corner of illumination and radius will allow to create shadows.

There should be a mod that scaled everything in UT about 1000%
then the lightmap resolution would be really small and useful
