I thought it was about time I asked about this as it’s been bothering me for years!
The behaviour of the colour smudge engine seems somewhat unpredictable or inconsistent. The main issue is the banding I get through a brush stroke. It seems to affect flatter brush tips more than round ones, and seems to get more pronounced as I reduce the brush size; This in turn seems to affect the opacity.
I’ve tried to isolate the cause, but not been able to narrow it down - it’s doesn’t seem to be related to pressure sensitivity for example.
Can anyone shed some light on this? - I couldn’t find any mention of it via search.
I’ve made a couple of example pages to demonstrate…
