Sliders / Joystick

Slider

A slider is a 1D controller that drives a single target.

Note

The target type of a slider cannot be changed after creation.

Target Types

Shape Key

Controls a Shape Key value on a mesh object.

Custom Property

Controls a custom property on a bone.

  • Only bone custom properties are supported
  • If the specified custom property does not exist, it is created automatically

Data Path

Controls any Blender property by data path. This is the most flexible target type.

Right-click a property in Blender and use Copy Full Data Path, then paste that path into the field. Numeric properties (float / int / bool) are supported.

Warning

String properties, and properties whose right-click menu does not show Add Driver, are not supported.

Mirror

Shape Key Mirror

Automatically creates a mirrored pair based on L/R suffixes. One track is split into halves; on screen, R appears on the left side and L on the right side.

  • Example: smile.L ↔ smile.R

Custom Property Mirror

Pairs targets by the .L / .R suffix in the target bone name.

  • Example: c_hand_ik.l → mirrored target c_hand_ik.r (the property name stays the same)
  • If the property name itself also has an L/R suffix, it is mirrored automatically as well

Warning

Mirror is only available for Shape Key and Custom Property. It cannot be used with Data Path or Joystick. Supported suffixes: .L/.R, _L/_R, -L/-R (case-insensitive)

Appearance

  • Handle Shape: Circle / Arrow / Square / Diamond
  • Height: L / M / S
  • Track Style:

Capsule / Line styles

Style Description
Capsule A rounded capsule-shaped rail
Line A thin rail. The handle becomes a tall rectangular shape

Keying Excluded

When Keying Excluded is ON, the slider bone name switches to the GEO- prefix. The handle shape changes to a special double-line icon so it can be distinguished visually.

With this setting enabled, the slider is excluded only from these keying sets:

  • Entire Character
  • Entire Character (Selected Bones Only)

Warning

If Auto Key is ON, those keying sets will still insert keyframes as usual. To exclude them completely, enable Preferences > Animation > Only Insert Available in Blender.

Reordering

You can manage the display order of sliders from the list in the N panel.

  1. Select a slider in the list (linked with bone selection in the 3D View)
  2. Move it with the UP / DOWN buttons
  3. Confirm the new order with Apply Order

Note

The Relocate Slider button appears beside each column's slider list and is used to move a slider to another column or container. If the list becomes out of sync after Undo / Redo, use Reload to resync it.

Joystick

Joystick

A joystick is a circular 2D controller. You can assign a different target to each of the four directions: up, down, left, and right.

  • The outer circle defines the movement limit of the handle
  • Drag the inner handle to operate it
  • Each of the four directions can have its own target

Per-Direction Target Settings

You can set a target type for each direction (Up / Down / Right / Left). Each direction has its own Range Min / Max and its own independent value range, but the default value is always 0.

Warning

Joystick does not support Mirror or Keying Excluded.
