UDK lighting issue (light affects meshes differently)

[Moshbeast]

Hiya so ive got a bit of an issue with my lighting I am working on a modular environement and the light seems to affect meshes differently

since i was wondering if it was a rotation problem i looked into this thread http://www.polycount.com/forum/showthread.php?t=94585&page=2

but unfortunatly i also tried to simply place the meshes into a new scene without rotating them the result was pretty terrible aswell

all the meshes have very similar UVs but there are minor differences

any ideas? please :(

this might have something to do with light maps and how lightmass handles them; have you tried adding a second UV channel to your meshes?

[Moshbeast]

yea they all have lightmaps and ive also applied the normal map to simple planes which were fine so something must be wrong with the mesh somehow

I am also having this problem.

For some reason UDK decides to randomly render my duplicated meshes different values.
