Re: Question about Normalmap
Nvidia would do the invert Y because that was how most game engines accepted normal maps. The problem then was that different 3D packages didn't always conform to this. What many do now is (depending on what they use, Maya/Max, etc) and to keep maps consistent for the context, is generate the normal maps and then do the invert to the Y green channel, in game. UE4 has setting to to this. xNormal and nDo also have settings if you want to do the invert.

Re: Question about Normalmap
Thanks! That's what I though, but I was just assuming xNormal info was accurate. nDo and the NVidia plugin only say invert axis, not positive nor negative, just invert from the default settings without telling you what are the default settings. Since both have different results, I wasn't sure anymore how a Y positive would look like.
