Defines the brush color.
Opacity refers to the level of transparency with which the color or eraser is applied. The Pressure setting is for the graphics tablet pen.
The Size option defines the diameter of the Doodle brush. The Pressure setting is for the graphics tablet pen.
Note that the radius of the brush tip depends on the Size X/Size Ysetting (Doodle object: Options tab): The internal bitmap will always be scaled to the Viewport size.
The Hardness setting defines the hardness or softness of the brush edge. The smaller the value, the softer, more transparent the edge. The Pressure setting is for the graphics tablet pen.
This value defines the intervals between color application during painting. Lower Opacity and Hardness values make the effects of this option more visible.
If active, a new Doodle Key will be created (if none already exists) at each new frame in the animation where doodling takes place.
