Constraints are not limited to positive strength values. Applying negative strength values (e.g., -100%) allows an object to perform the inverse action of its target. This technique is useful for creating complex rigging behaviors, such as mirrored movements or counter-rotations, with a single control point.
- Inverse Motion: Negative strength is a powerful shortcut for creating mirrored interactions (like doors opening in opposite directions) using only one animated controller.
- Offset Importance: For Translation constraints, using the "Offset" toggle is often necessary to prevent the owner from snapping directly to the target's position while moving inversely.
- Consistency: This property is also keyable, allowing you to switch between direct and inverse behavior within the same animation.
