UIShadow

Inherits from: UIComponent → UIBase → Instance → Object

UIShadow renders a drop shadow below its parent UI instance. Key features include:

Adjust the shadow's bluriness with BlurRadius.
Adjust the shadow's color and transparency with Color and Transparency.
Adjust the shadow's position and size relative to the parent with Offset and Spread.
Add multiple shadows under the same parent and adjust their render order with ZIndex.
If the parent is rotated with GuiObject.Rotation, the shadow will also be rotated.
If the parent has round corners with UICorner, the shadow will also have round corners.

Limitations

UIShadow does not support text. If you add a UIShadow to a TextLabel or TextButton, it renders a shadow of the object's rectangular bounding area, not of the text.
UIShadow does not support inset shadows.
UIShadow does not support Path2D.
You cannot apply textures or UIGradients to a UIShadow.

UIShadow.BlurRadius

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.

Field	Value
type	UDim
security	{"read":"None","write":"None"}
thread safety	ReadSafe
category	Appearance
serialization	{"can_load":true,"can_save":true}
capabilities	["UI"]

UIShadow.Color

This property determines the shadow's color.

Field	Value
type	Color3
security	{"read":"None","write":"None"}
thread safety	ReadSafe
category	Appearance
serialization	{"can_load":true,"can_save":true}

UIShadow.Enabled

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

Field	Value
type	boolean
security	{"read":"None","write":"None"}
thread safety	ReadSafe
category	Data
serialization	{"can_load":true,"can_save":true}

UIShadow.Offset

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.

Field	Value
type	UDim2
security	{"read":"None","write":"None"}
thread safety	ReadSafe
category	Appearance
serialization	{"can_load":true,"can_save":true}
capabilities	["UI"]

UIShadow.Spread

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.

Field	Value
type	UDim2
security	{"read":"None","write":"None"}
thread safety	ReadSafe
category	Appearance
serialization	{"can_load":true,"can_save":true}

UIShadow.Transparency

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

Field	Value
type	float
security	{"read":"None","write":"None"}
thread safety	ReadSafe
category	Appearance
serialization	{"can_load":true,"can_save":true}
capabilities	["UI"]

UIShadow.ZIndex

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.

Field	Value
type	int
security	{"read":"None","write":"None"}
thread safety	ReadSafe
