Lightning Issues

Hello. I am not that familiar with this world but I do know some things. I have been modeling modular construction objects for a while and I recently textured some of them. When I put them together in UE5, there is a slight but visible seam. Does anyone know what I need to do? Thanks in advance!

-Using BLENDER for modeling

do you get the same issue in ue4? if you do, then it might just be a simple fix of just marking your seams in blender

Well, I lined up the UVs of the mesh and now there is no seam… Thank you. BTW it did that too in UE4.
