Shadow and lights doesn’t project in the mesh the the normal map are appyed

Hi, I’m having a problem with the projected shadows of the meshes. When I apply a material to the object turns dark does not project the light and shadow of the directional light. When the mesh has no material I can see the shadows and lights, in the Light Only view mode I can see it too but when I change to Lit view mode the mesh light disappear when the material are applied.

Normally happens when I apply the normal map to the material, but I don’t know if the textures and normal maps are the problem or the UV map of the model are bad.

I’m using UE 4.16.3 and is my first time using it for archviz.
Please, Help
