Incorrect texture or material map
I have an issue with a texture or material map of some of imported to UE4 meshes. I create my meshes in 3ds max. The problem has started only recently. Below steps I follow:
created a mesh attached all elements to unwrap and export as one mesh unwrapped 2 map channel (image below 'a') exported (image below 'b')
* imported into UE4 (image below 'c')

Finally I found a solution to my problem. As MacDx mentioned it was related to my UV map. I focused on a second channel but at the end channel 1 was my main problem.
1st UV channel is usually for standard baked textures to be mapped from
2nd UV channel is for the lightmap.
Whenever I've created UV map in 3ds max for channel 1 &2 I never "Collapse" it and that caused me a problem. If modifier "Unwrap UVW" is not collapsed 3ds max can't save it.
Bellow 3ds max steps for anyone who would have similar problems to mine:

The problem are the UVs
Those UVs are not apt for use. It looks like the default unwrap is separating a lot of tiny faces which is what is causing the problem here. I'm not an expert on 3ds Max but I would suggest doing a box UV mapping of this object and then polish them if needed.
Look at this example
No tiny faces or vertex by themselves
