Black trees in terrain after Lightmapping

I already read some posts about this problem, but none of them helped me.

Anyone khow how to solve this problem? The terrain is very bright but the trees on it are very dark…
I am using baked only for all lights…

Thx in advance!

Pics would help but I am assuming you made the tree’s in an external program like 3DSM/Blender etc etc and sounds like you might need to remake the lightmap. Sounds like it didn’t bake right. Pictures would definitely help though.
