Why am I getting a shadow on the seam of my two identical walls?

Hey,

i have these 2 meshes (they are the same) connecting at the edges. The mesh always generates this shadow althoug i want them to be seamless.

I tired like 20 different lightmap layouts. Even with a reduced layout (like in picture) i have the same effect. (ofc i tried it with alle compontents too…)

Any advice?

Silly question, but have you rebuilt the lighting?

Yep, the solution was: Generate\Compute Normals on Import
