Fixing inverted normal maps

[SpinX]

I made my normal map by mixing a fabric normal map and a high poly backed onto low poly in blender. In rendering it looks great but in fallout 4 it looks inverted. The high parts appear low and the shadows show on the the same side that are exposed to light.

I saved in bc5 using gimp plug in. I tried inverting the green channel it fixed some parts but it messed up other parts.

 

What's the correct way of doing things if I don't have access to Photoshop and the Nvidia plugin

Edit-2: I've read your question wrong the first time. It might possible that Fallout 4 requires certain channels to be inverted. I've seen it vary before. I'm not sure, so you might wait for someone who knows.

 

Edit-3: Check out this on LL about 3Dc.
