Property

Description

Casting SourceSets the source for the shape of the shadows. Unity displays the shape as a white outline in the Scene view. The options are the following:
  • Sprite Skin: Uses the bounding box of the bones defined in the Sprite Skin component attached to the GameObject. This option is available only if you add a Sprite Skin component to the GameObject.
  • Sprite Renderer: Uses the shape defined in the Sprite Editor window. Uses the shape in the Skinning Editor tab if the GameObject has a Sprite Skin component, otherwise uses the shape in the Custom Outline tab.
  • Collider 2D: Uses the shape defined in the collider component attached to the GameObject. This option is available only if you add a collider component to the GameObject, for example a Box Collider 2D component.
  • Shape Editor: Uses the shape defined in the Edit Shape property.
  • None: Casts no shadows.
Casting OptionSets how the GameObject casts shadows. The options are the following:
  • Self Shadow: Casts shadows only onto itself.
  • Cast Shadow: Casts shadows only onto other objects.
  • Cast and Self Shadow: Casts shadows onto itself and other objects.
  • None: Casts no shadows.
The default is Cast Shadow.
Target Sorting LayersSets the 2D sorting layers that receive shadows from this GameObject. The default is Everything, which means other GameObjects on any sorting layer receive shadows.
Trim EdgeIncreases or decreases the size of the Casting Source. A Trim Edge value of 1 means the Casting Source is its original size. Lower values decrease the size. This property is available only if you set Casting Source to Sprite Renderer. The default is 0.2.
Alpha CutoffSets the minimum alpha value a pixel must have to cast a shadow. The default is 0.1. This property is available only if you set Casting Source to Sprite Renderer.
Edit ShapeIf Casting Source is set to Shape Editor, select this button to edit the shape of the shadow. Unity displays the shape as a white outline in the Scene view. Click and drag the white circles to move the points, or click a line to add a point.
PositionSets the position of a point on the shape. This property is only available if you select Edit Shape.
