Shading Problems with LODs


I am having problems with shading on my LODs.

Lod0 is just fine as in this pic.
But when I pull back from the models, light map doesnt seem to like lod1

This is really annoying and I dont know what to do. I am importing them from 3ds max and all are one smoothing group. Tried different smoothing groups but things get even worse.

I will post on Ue forums never again
