    I never had this problem before. Not in any engine, i only noticed it was an issue because another user said my material was flat, it wasn't flat it was inverted LOL

    .... But anyway Thank you very much Tidal Blast

    Flip Green Channel solved it

    p.s.
    Thanks for reply Tidal Blast....you missed some info so ill post it here because it may help new users.

    Unreal engine (1 - 4):
    • Black = low
    • White = high.

    The widget colours also correspond to this colour key
    • R= X
    • G= Y
    • B =Z




    We need control instead of automatic texture imports.

    Normal maps are inverted? why?




    Solution 1:
    • Expand all categories in the texture editor (right click texture to show properties)
    • Flip the Green Channel


    Solution 2:
    • In the Engine.ini search for this:

    Code:
    [/Script/UnrealEd.EditorEngine]
    FlipNormalMapGreenChannel=False
    • X:\Users\YOURNAME\Documents\UnrealTournament\Saved\Config\Windows


    more useful info:

    Unreal Engine 4

    • X - forwards, backwards
    • Y - left, right
    • Z - up, down
    • Pivots = Roll, Pitch and yaw

    • R= X
    • G= Y
    • B =Z
