Maya to Substance Painter to UE4

Im fairly new to substance painter and design and ive created the texture above for one of the models i have created (Created in Maya). when i export out of Substance Painter into Unreal Engine 4 it seems the texture doesn’t apply to the model correctly. Not sure if this is an issue within me exporting from Substance to UE4 or the importing process into UE4. If anyone has any insight would be much appreciated.
