Random light bleed

HAWK12HT

Hey all, ok every lightmap UV is on UVW grid and there are no visible seams and bugs except on few areas where couple of closed meshes intersect each other.

like one mesh is inside a little of another mesh to form another object, on these areas im having light bleeding. It was a known issue if you model stuff like that in 3d program but in UDK you can do it. EPIC level Deck is filled with this sort of stuff and there is no bleeding like that.

Any idea why is this ?

Building level with High/Production quality fixes most of those issues.

yup tried that already, it was still noticeable.

I got the same probleme in mu current project, its not that big of a bleed but still is. I'm also sure that my 2nd uv set is ok with no overlap and I got the same kind of result you're experiencing. I tried cranking up the lightmap resolution but no better result. I hate lightmaps...thats it XD

If you're talking about this:

That doesn't look like lightmap bleeding, that's just the default SSAO, which won't get a perfect silhouette of your mesh.

Pretty sure he's talking about that giant blue/grey tinted stain in between the arches

....or, actually, is it the other way around? are you talking about the orange light that's bleeding in?

I would expect there to be a blue stain ... the meshes surrounding the area are blue. If you want to remove the stain you can turn UDK's GI off... but then you won't get any cool bounce light.
