Problems on importing fbx and materials

Hi. I am new to UE4 and I have created a character in maya and imported the fbx file into the engine. My model have 2 materials and one of them is acting weird. On the same material only some of the texture placement is correct. I tried to add a TexCoord into the material and when I change the Coordinate Index from 0 to 1, the wrong part of the texture get fixed, but the other part becomes weird. Did I did something wrong in the process of importing the fbx?
