This property determines the shadow's blurriness. A larger value makes the shadow's edges appear softer.

Note that the scale factor of this UDim property is relative to the parent's width or height, whichever is shorter. This property must also be non-negative; a negative value will be treated as 0.

This property determines the shadow's color.

This property determines whether the UIShadow is visible. Default is true.

When true, the shadow appears on top of and inside the parent. When false, the shadow appears behind the parent.

Defaults to false. This property has no effect when Mode is ApplyShadowMode.Text.

Determines whether the shadow applies to the parent's shape or text. Defaults to ApplyShadowMode.Shape, which renders a shadow for the parent's rectangular area.

ApplyShadowMode.Text renders a shadow for text in a TextLabel, TextButton, or TextBox. On other classes, text mode renders no shadow.

Shape mode and Text mode shadows can coexist under the same parent.

The following properties have no effect in text mode:

• Spread
• Inset
• ShowBehindParent

This property moves the shadow relative to the parent's position. The X scale factor is relative to the parent's width, and the Y scale factor is relative to the parent's height.

When true, the entire shadow is rendered. When false, the parent's shape masks the portion of the shadow directly behind it. Disabling this property prevents a shadow from obscuring content behind a transparent parent.

Defaults to true. This property has no effect when Mode is ApplyShadowMode.Text or Inset is true.

This property expands or shrinks the shadow relative to the parent's size. The X scale factor is relative to the parent's width, and the Y scale factor is relative to the parent's height. Properties that are relative to the parent's size, such as the scale factors of BlurRadius and Offset, are not affected by Spread.

This property has no effect when Mode is ApplyShadowMode.Text.

When Inset is true, positive Spread values expand the shadow toward the center of the parent instead of outward.

This property sets the shadow's transparency, with 0 being fully opaque and 1 being fully transparent.

If a UI instance has multiple shadows, they are rendered in order of increasing ZIndex. Since all shadows are rendered below the parent instance, ZIndex can only be negative.
