Copy Scale Constraint

The Copy Scale constraint forces an object or bone to match the scale of a target.

Options

Copy Scale constraint.

Target

The object or bone whose scale to copy.

Axis

The axes for which to copy scale factors.

Power

Raises the target’s scales to the specified power. This is done before applying the Offset.

Make Uniform

Instead of applying the scale for each individual axis, apply a uniform scale to all axes that achieves the same overall change in volume.

Offset

When enabled, the target’s current scale (from all its constraints) is not copied over, but multiplied with the owner’s original scale (from its preceding constraints).

Additive

When Offset is enabled, don’t use multiplication, but add the owner’s scales minus 1. This option is kept for backwards compatibility, but generally makes no sense and should not be used.

Target/Owner

The spaces for retrieving the scales from the target and for applying them to the owner.

Influence

How strongly the constraint affects the owner.

Tip

Depending on the settings, Power can be used instead of Influence to get a better-looking result.

Tip

To copy the scale from one axis of the target to all axes of the owner, disable the other axes, enable Make Uniform, and set Power to 3.
