GlowingPotato> Glad that helped you :) Ignore my previous question... Forgot that the Texture Map node was a group as any. If you enable advanced mode and look for yourself you can see that the "ConvertToLinearSpace" = x^2.2. At least in Maya 2015 which I have at home. I've got 2016 at work.
@shaderfx thanks for your assistance, i really appreciate. The gpu model is Gigabyte windforce R9 280 with up to date drivers. @kodde That does it! Checking the box convert to linear space on the texture map node does the trick, no more double gamma corretion! Thanks kodde!
