At least from screnshots your pen produces the same behaviour - even small stepping in the ends of the brushstrokes (but it appears when I reduced tablet's pressure sensitivity to min value).
Oh, that explains a lot, thanks. But I noticed that's true if my tablet driver magic option `support TabletPC` enabled (it enabled by default). But if this option is off, the AR does not reproduce pressure sensitivity despite the stylus settings you specified.
Yeah, probably the pen I use has the same issue, although it's Huion pen.
Which pen do you use? It would be interesting if you post AR screenshot with your oil brush strokes with pressure-responsive option on.
