Is it supposed to show seams in the uv map when using IBL?

[jnmaloney]

I tried unwrapping a model using lightmap pack in Blender, and then the lighting was all messed up in Filament. So I tried a different uv unwrap and used Filament material with IBL only. The lighting shows the uv seam on the model.

Is this expected and if so how can i fix my models?

Edit: The problem can go away if I compile new materials instead of using textured.filamat.

Can you link the Blender file you're using?

I'm still getting used to Filament, but I think that it is not supposed to look like that and I made some mistake with the material, because I was using the default textured material without giving a normal map.
