Different Lightmap on Adjacent Surfaces

hi there,

i have a really silly problem, look at this picture please :

i can’t understand why a wall is whiter than the other.

  • the walls are on the same 3D max model. Faces are well oriented.
  • they have the same lightmap, resolution 512.
  • to try to solve this problem i stitched them in the lightmap UV’s (before they were far from each other) but no change.

can you explain me a little bit what’s happening ? how can i solve this ?

thank you!

i solved it by augmenting to Production instead of High the lightmap quality, and tweaking a little with world settings…now i ve some blurry textures in darker areas, i should open a new thread for that…
