Rotation Constraint

Summary

The Rotation Constraint allows an object to copy the rotation values of a target object. Similar to Translation and Scale constraints, it features strength controls, axis limits, and offset options, enabling automated rotation-based motion and complex relationship between objects.

Step by Step

1. 00:17
   Adding the Constraint

   Select your object, go to the Inspector, and add a Rotation Constraint from the constraints menu.
2. 00:31
   Setting the Target

   Use the target selector to pick the object that will drive the rotation. Once set, the owner will match the target's rotation angle.
3. 00:46
   Adjusting Strength

   Use the Strength property to customize how much of the target's rotation is applied to the owner. This property can be animated for dynamic control.
4. 00:58
   Configuring Limits

   Define Minimum and Maximum degree values to restrict how far the owner can rotate, even if the target continues to spin.
5. 01:06
   Duplicating with Constraints

   When duplicating a constrained object, the new copy retains the link to the original target automatically.
6. 01:31
   Animating the Source

   Animate the target object's rotation in the timeline; all constrained owners will follow according to their individual strength and limit settings.

Notes About Current Rive

• Efficiency: Using rotation constraints allows you to animate one main controller and have multiple secondary objects follow, saving significant keyframing time.
• Offset Toggle: Use the Offset option if you want the owner to maintain its current rotation relative to the target's starting angle rather than snapping to match it exactly.
• Complex Rigs: Rotation constraints are essential for gears, eyes, or mechanical parts where synchronized rotation is required.
