If your digitizing tablet supports the Tilt feature, then this brush can be useful to you.
This is a pen to be used for calligraphy.
Some styles of calligraphy require different pen nib angles for different strokes.
This brush is designed so that only one tip at a time is active.
There is no blending between the tips.
Tip one is a brush tip at 30 degrees and is active when the stylus is held vertically to the tablet.
Two Colors - Enable Color Jitter in sub-tool settings for dual color to help with troubleshooting tilt. The color will be an easy way to spot whether brush tip one or two was active.
1 - Blue is the active color in this demonstration. You may have a different active color.
2 - Color Jitter is on.
3 - The Hue of the current active color is shifted by 225.
