    Lightwave getting odd results with a normal map from Gaea

    Hello All,
    I've been having a lot of fun with the Gaea terrain tool, exporting displacement maps and textures for rendering in Lightwave.

    I've just started trying the Normal Map build from Gaea, but I'm getting odd results.

    To be specific, I'm getting bright areas on some cliffs, acting like they've received a serious boost in diffuse.
    On examining the map, it has some green areas which look to be on the cliffs, whereas I normally expect the colours to be dominated with purple, and a bit of red and blue.

    I attach a smaller version of the map.

    Is this some flavour of Normal map that LW doesn't like?
    (The original is 8k x 8k, PNG format, 16 bits per colour channel).

    Any ideas on how to work around this?
    Maybe editing the map to remove the green, or perhaps to generate a new one from a 16 bit bump map?

    Any software solution needs to handle 16 bit channels and BIG images.

    Thanks in advance for any suggestions,

    PS - I'm still mainly using Lw 11.6
