The Scale constraint lets you constrain the scaling of one object relative to the scaling of one or many other objects.
Scale constraint
An asset, model, or other object whose orientation derives its size from the Source object(s). Also known as the “child” object.
Sends scaling information to the constrained object. You can have multiple source objects for this constraint. Also known as the “parent” object.
The following Scale constraint settings are found only in the Properties window when the constraint is selected in the Scene browser:
| Property | Description |
|---|---|
| Scaling Offsets XYZ | Use these fields to move the constrained object from the Source object(s). You can set key animation on any of these settings.These fields are disabled if the Lock option is activated. |
| Blend Method | The Blend Method menu lets you specify a way in which the Scaling is calculated when you are using multiple Source objects. There are two options:Geometric: a logarithmic method compatible with Maya’s scaling constraints.Average: which calculates based on the average scale of the objects. |
| Constraint Axes | Activating or disabling these axes affects whether the constrained object is affected by the source objects’ movement on this axis. Affect X: When active, the constrained object is transformed along the X-axis with the constrained object. Affect Y: When active, the constrained object is transformed along the Y-axis with the constrained object. Affect Z: When active, the constrained object is transformed along the Z-axis with the constrained object. |
| (Source Object) Weight | Use this setting to give different amounts of influence to source objects. |
