Non-uniform Scale Component

The Non-uniform Scale component allows entities to be scaled by different amounts along each local axis. It can be added by clicking the Add non-uniform scale button on the Transform component.

The Non-uniform Scale component is incompatible with certain other components which cannot be non-uniformly scaled without fundamentally changing their character. For example, it is incompatible with Sphere Shape component because non-uniformly scaling a sphere would result in an ellipsoid and break the characteristic symmetry of the sphere.

To avoid problems with skew, non-uniform scale is only applied to the current entity and does not propagate to its children.

Compatible components

The following components are compatible with Non-uniform Scale:

Incompatible components

The following components are incompatible with the Non-uniform Scale component because non-uniform scaling would break fundamental assumptions made by the components or because they would require major work to properly support non-uniform scale:

The following components are currently incompatible because they are not yet supported, but do not have fundamental reasons making compatibility difficult to add:

EBus Request Bus Interface

NonUniformScaleRequestBus is the request bus for the Non-uniform Scale component.

For more information about using the event bus (EBus) interface, see Working with the Event Bus (EBus) system .

Use the following request functions with the EBus interface to communicate with other components.


Returns the entity’s non-uniform scale.

Parameters None

Return Entity’s non-uniform scale value. Type: Vector3


Sets the entity’s non-uniform scale.

Parameters New non-uniform scale value. Type: Vector3

Return None


Registers a handler for the AZ::Event raised when the entity’s non-uniform scale is changed.

Parameters Handler for non-uniform scale change events. Type: NonUniformScaleChangedEvent::Handler

Return None

Editor Automation

The component type id for the editor Non-uniform Scale component can be accessed for editor automation using the following.


For example, a Non-uniform Scale component can be added and the scale modified as follows.

nonUniformScaleComponentId = azlmbr.editor.EditorNonUniformScaleComponentTypeId
azlmbr.editor.EditorComponentAPIBus(azlmbr.bus.Broadcast,'AddComponentsOfType', entityId, [nonUniformScaleComponentId])
azlmbr.entity.NonUniformScaleRequestBus(azlmbr.bus.Event, 'SetScale', entityId, azlmbr.math.Vector3(1.0, 2.0, 3.0))
