Weird Light issue!

ok… finally got my 1 mllion polygon head inside the editor with no weird mesh issues. looks great. but now i have this issue… the mesh is 1 foot big inside 3ds and exports as a fbx to ue4 with no issues and the lighting is 100% good. but now if i try to add eyes or let alone a simple sphere with correct unwraping on channel 1 and 2 I get this odd light issue. Notice how light has no effect on it? its very dark. its not totally dark… you can see the texture if i bump up the light extremely high but everything gets overblown. almost like a scale issue. anyone come across this issue? for the sake of trying to debug this i just created a simple sphere and unwrapped it and imported it… and its dark all the time… any advice? heres the pic
