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.

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

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

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

Thank you!
