Enable Pen Pressure in Astropad Studio for Windows
Pen Pressure Sensitivity
Astropad Studio supports pen pressure sensitivity using the Windows Ink tablet driver API. You can adjust the pressure curve in the Studio sidebar by tapping the red ring button > Pencil & Stroke > Pressure Curve.
Below are steps to enable pen pressure in common programs. If your program isn’t listed, check for a similar setting or let us know.
Blender
Clip Studio Paint
Drawpile
Krita
Paint Tool SAI
Toon Boom Harmony
TV Paint
Zbrush
Some programs like Photoshop CS6 do not support the Windows Ink API, so pen pressure will not work with Astropad Studio for Windows.

In Blender’s menu bar, go to Edit > Preferences > Input > Tablet and change Tablet API to Windows Ink.
Enable Pen Pressure in Clip Studio Paint
With Windows Ink enabled, in Clip Studio Paint’s toolbar, go to File > Preferences > Tablet and select the use TabletPC option.
Enable Pen Pressure in Drawpile
Go to Edit > Preferences > User Interface. Check Enable Pressure Sensitivity and Use Windows Ink. Then restart Drawpile.

2. Go to Settings > Configure Toolbars and select mainToolBar
3. In the left menu under Available actions, select the option for pen pressure (Use Pen Pressure or Pressure Usage). Click the arrow to move it to Current Actions, then click OK or Apply.
4. Ensure the File toolbar is visible. If not, go to Settings > Toolbars Shown > select File.
5. Enable the pen tip icon to use pen pressure, located next to the undo and redo buttons.
6. Restart Krita.
Enable Pen Pressure in Paint Tool SAI
Pen pressure works only in the Developer version (SAI Ver.2). It is not available in SAI Ver.1.2.5 or older. Astropad Studio uses the Windows Ink API.

In TV Paint’s menu bar, go to Edit > Preferences > General and change Tablet to Ink.
