GUI Slider User Manual

GUI Slider is an add-on that lets you place slider- and joystick-style controllers directly in the viewport to control Shape Keys, bone custom properties, and Data Paths.

Basic Workflow

  1. Select the armature you want to add controllers to
    • If the armature's scale is not 1, the sliders will not display at the correct size.
  2. Switch to Pose Mode
  3. Open N Panel > GUI tab
  4. Press Add Container to create a container
    • Use Slider Container if you want a row of sliders
    • Use Joystick Container if you want to group four-direction controls
  5. Press Add Slider to add a slider or joystick inside the container
  6. Choose a target type
    • Shape Key
    • Custom Property
    • Data Path
  7. Set the target object or bone and the property name
  8. Adjust the range and appearance as needed
  9. Move the controller in the viewport and confirm that the value changes correctly

Base Scale

For non-human-sized models (small characters, giant mechs, etc.), set Base Scale from the panel menu (▼) to match your model's size. When creating a container, the scale value will be reflected in the input field.

  • 1.0 = human-sized scale
  • Quick View display scale is auto-compensated
  • The setting is stored per armature

When To Use What

  • Slider: Use it when you want to control a single value
  • Joystick: Use it when you want to assign different targets to Up, Down, Left, and Right. Useful for driving four-direction facial Shape Keys such as eyebrows or mouth shapes with one controller.
  • Dual Controller: Use it when you want to add a secondary helper controller to an existing bone
  1. Create one Slider Container
  2. Add a single slider that targets a Shape Key
  3. Confirm it works, then add mirroring or columns if needed
  4. Once the number of controls grows, switch to Quick View

Quick View

Quick View lets you gather scattered containers at the front of the viewport and view them as a single overview. Regardless of where you are in the viewport, it always shows the same layout. Even when you have many containers, many columns, or containers placed in different locations, you can efficiently adjust parameters in one place.
