The wall is made of blocks of identical wall models with the same UVs. How to get rid of these seams on the lightmap?

enter image description here enter image description here enter image description here

How I made this scene with this models:

  1. I made 3D model of the wall element in Blender.
  2. Import the wall element in Unity and generate UVs in FBX settings.
  3. I made walls from the wall element in the Scene and marked all wall elemets as Contribute GI.
  4. Next I baked lightMap and get this seams.

  • \$\begingroup\$ Images should be embedded, not linked externally, and you should include the steps of how to create a model that exhibits this problem. Do not assume that it is universal to any model made in Blender. \$\endgroup\$
