in up is I am deal with in u3d sg , but it result not true I think so ,down is invert in photoshop
why had difference?
pls tell me

Had the same problem. Remap and Subtract nodes didn’t help. Eventually if i got it right this happens because of the “Precision” of texture’s color. If you want your texture to be inverted correctly you need to use images with higher pixel depth. The higher it will be the more precise result you get.
So to fix this you can set property’s precision to float6584605--747886--upload_2020-12-3_13-40-53.png

And maybe manually set your desired format in texture’s import settings.6584605--747892--upload_2020-12-3_13-43-52.png

Also you might try to uncheck “sRGB (Color Texture)” in import settings as well for a grayscale image
