Prolem with normal map exported from Blender

I have baked normal map in Blender and when I am exporting it in UE. Normal map does not look correct. How can I fix it. I use Blender 2.74 version.

Why are you exporting your texture from blender ? Why don’t you just export it as a png and then import it in UE4 ?

Double click on the texture in the content browser, find the “Flip Green channel” under the “Textur” options, enable or disable it.
Done.

I was tried this method. The result is the same.

Thank you!
