Static mesh mult/sub object material not working

I create a simple door mesh in 3ds MAX and used multi/sub object(i applied 2 materials) to the mesh. And i exported and imported to UE4 without error message. But the material was not applied to the door mesh.
(I applied UVW Map and used bitmap images as textures).

What am going wrong …

Make sure you’re using the Standard material in 3ds Max and that your texture maps use resolution values that are multiples of 2

I was using Architectural Mat and changed it to Standard material. It works now.
