For some reason nDo2 is adding random noise to all my photo-generated normal maps..
Below is a picture of a dummy gravel texture (512x512). I´ve run two different photo-normal presets: full spectrum and "soft and large".
I also added 3 grey lines to the dummy texture and executed the presets once more and you can clearly see that nDo2 is adding some random noise on completely flat areas - and this is on a completely clean install (Ive not tampered with any settings).
(I´m creating the photo-normal from the active document)
