- DENSITY - Bristle engine in Krita have great potential and I find it really unique. It is strange that density parameter isn't exposed to be controlled via pen pressure. It is not exposed to controllable parameters in Popup palette. Available parameters are (Brush HUD Configuration): Angle, Auto Spacing, Flow (???), Opacity, Size, Spacing. - FLOW - Flow doesn't exist in bristle brush settings interface but it is exposed in Popup palette. It doesn't have any effect on bristle brush behavior either. Something is confusing here. ... I think Density should/must be pressure controlled and exposed to Popup palette. I wonder if Density can become Flow in bristle engine?
