Context: I'd like to use the normal maps generated by the Ocean Modifier in Unity.

The ones I've generated average 50% in both the red and blue channels and nearly 100% in green which seems very unusual for a normal map. My best guess is that they're in some kind of world or object space, but attempting to use them in a shader in Unity yields clearly incorrect results. Given that Blender's world space is Z+ and Unity's is Y+, it's possible the channels need to be swizzled but I couldn't find a combination that worked.

So, what texture space are the Ocean Modifier normal maps in?
