To use:

Put an Animator component on your Body. Assign the BlinkController animator controller.

If you want to disable blinking in a gesture, duplicate the "SuspendBlink" animation and add your own properties to it.
Make sure the animator behavior alternates between enabled and disabled every frame.

Alternatively, you can simply copy the keyframes from the SuspendBlink animation and paste them onto an existing one.

If your blinking is on a mesh not called "Body" (or if your mesh is further down in the hierarchy),
just add the animator controller to that mesh. On the suspend blink animation, press F2 on the "animator behavior" property to change its path.
