I have a strange project where I want to animate the shadow of a physical object. The idea is to make a digital version of the object and animate it in blender and then render the shadow of the object on plane to a video. Then play that video on a tablet and place the physical object on top. I watched a video about baking here: https://www.youtube.com/watch?v=sB09T--_ZvU
Which will get me the results I need for one frame. Is there a way bake an entire animation?
