Animating multiple objects with one dummy
Based on a tutorial I watched last night I created this quick animation. I started with one square added one dummy helper and one Exposetm. I linked the square to the the Exposetm then to the dummy. Basically the dummy controls the height of the square based on how close or how far it is from the square. After that it was a matter of making copies of just the square and Exposetm. Doing so links all copies to the single dummy, then creating an animation for the dummy, rendering and done.
