My name is Elianna. I have a Bachelor of Fine Arts in Illustration. I have used PaintTool SAI for over seven years with a variety of different tablets including a Wacom Bamboo and a Wacom Cintiq 16”. I’ve troubleshot every issue there is, and am here to help you save time and frustration. 

In this post, I am going to explain some solutions to fix the stabilizer not working in PaintTool SAI. 

Let’s get into it! 

Key Takeaways

  • To access PaintTool SAI VER.1 Stabilizer settings, check the box Adjust feeling of brush stroke of stabilizer 1-15 similar to Ver.1 in Help > Options > Preferences
  • Try basic fixes first before messing with PaintTool SAI options. 
  • Make sure your tablet driver is up to date. 
  • Change the TabletMouseSimulation in misc.ini value to 1 or more.

What is the Stabilizer in PaintTool SAI and How Does it Work? 

The Stabilizer is a brush setting that controls the smoothness of freehand-drawn lines in PaintTool SAI. Similar to the smoothing bar in Photoshop, this setting is useful for customizing your drawing experience and can help you transition from traditional to digital drawing much easier. 

The stabilizer is located above the canvas and has a variety of settings from 0-15 and S-1-S-7. 

If you have recently updated from Ver.1 of PaintTool SAI to Ver.2 of PaintTool SAI you may notice a slight difference in the stabilizer. To access the Ver.1 Stabilizer settings follow these steps:

Step 1:Click on Help > Options. This will open the Options menu. 

Step 2: Select Preference. 

Step 3: Scroll down to Brush Tools and check the box Adjust the feeling of brush stroke of stabilizer 1-15 similar to Ver.1.

Step 4: Click OK.

This is just an option for those who prefer the Ver.1 stabilizer. Personally, I do not notice a difference, but this can be a quick fix for those who are looking to maintain the Ver.1 feel.

Onto the list!
