Do 5 identical moving parts require 5 sets of keyframes

Making a camera shutter. It has five identical blades that swing to the center of the camera’s aperture. The shutters are driven by rotating an “actuator”, a slotted ring.

Looking for a labor saving technique.

Not a huge job to create a set of keyframes for each of the five shutters, but since they are identical parts, and swing through identical rotations, it seems there might be a short cut.

Example attached. One blade of the shutter has been animated. The other four are yet to be animated.

Thank you for your insights. Michael

The easiest way is to simply use Rhino’s ‘ArrayPolar’ command on Object 0, hence creating 4 copies of the object including its keyframes.

Thank you Luc, this worked immediately. All the keyframes were faithfully copied. Michael
