    I would say your resolution is too low.
    World machine produces 513x513 at minimum.

    Hello!

    I downloaded your image and tested it. The issue is actually that 16 bit PNG files get downgraded to 8-bit at some point in the import pipeline. I will get a bug filed for that.

    I tested converting the image to a 16-bit TIFF file, and it imported correctly without the quantization.
    (Just make sure you select "R 16 bit" as the texture format)

    Thanks.
    Which software did you used to convert to tiff? I tried paint.net, it seems it convert to 8bit tiff.
