I have a fbx, and in ue4 i want to change its material,it seems that the fbx can't use materials with displacement map, and other kind of materials are ok. i want to know what's the problem, is the fbx wrong?

Hello Eryang, can you show us an image of the situation at hand?

The images below show the situation.

If i change the materials of the fbx, it sometimes cannot get it, and turned to the first picture. I had tried many times, it seems that when the material has a displacement map, it will turn to the first situation.

The materials i use are certainly ok ,I tried it in other models.
So I guess maybe the fbx is wrong,but how I change it?
