Making 2 placed to each other objects have the same shadow

So I made 1 piece of sidewalk in blender and then exported to Unity.I want to duplicate the peace and combine it with the duplicated peace to make a long sidewalk. The problem is is that the peaces are shaded separately and it looks bad if I put them next to each other. Here’s an image so you all can understand better:

If anyone knows the problem or knows how to fix it I would really appreciate if you could tell me,thanks.

The problem is your Vertex Normals (or Smoothing Groups…or whatever Blender calls it). You should either give the sides of the sidewalk (the faces that meet each other when you put them side by side) their own smoothing group, or delete them.

Thanks man! I deleted the side faces and it fixed the problem :smiley:
