Deformed Normal Map

Hi! I’ve almost completed my first model (im new and im still learning the basics) I’ve been able to solve the rest of the problems by mystelf but this one is giving me a bad headache. I did the high poly and the normal map on Zbrush. I imported them to Maya and all seemed okey, but then i exported everything to UE and now the normals are a like inside out. Specialy the eyebrows, look at them, its like they go inside the skin, instead of sticking out. I dont know what is causing this, its not the normal map because its working fine on Maya. I exported the mesh as a fbx by the way. ¿What do you think it can be causing this? D:

I just fliped the green channel, that was the problem :smiley:
