Clip Studio Paint : Direction of Pen

Since some of the custom Clip Studio Paint brushes I’ve made use this feature, I’ve written this post as a quick reference.

In Clip Studio Paint, brushes have a “Direction” setting. This determines the rotation of the brush shape when it’s painted onto the canvas.

The direction of a brush can have dynamics that are based on certain inputs like pen direction, pen rotation or direction of line. This post describes how “Direction of pen” works.

Direction of pen is the direction of pen tilt, as opposed the amount of pen tilt (how much the pen is horizontal or vertical). Pen direction is the angle of the pen you see when you look straight down on your drawing surface.

Some custom brushes are designed with this in mind. This means they work best when the device supports this feature. Most EMR pens that support tilt usually also support detection of pen direction, as they rely on the same underlying technology.

If your device doesn’t support this feature, Clip Studio Paint will ignore it. The brush will usually default at a zero angle, as if the pen was pointing forward. In this case, you can change the “Direction” setting slider to suit your needs.

Some pens and tablets that include pen tilt and direction:

  • Wacom Intuos Pro (including Intuos 2 to 5)
  • Wacom Cintiq (and Mobile Studio series)
  • Apple Pencil
  • Microsoft Surface pen
  • Some Huion Pen tablets/screens since 2018.
  • Some XP-pen tablets/screens since 2019.

Make sure you check your pen tablet/pen screen’s official website to see if it supports tilt and pen direction.
