For those of you with a fast computer, Soft Body Physics can offer up all kinds of powerful animation effects, including this simple skin-healing effect shown in the video link further below. You can get grounded in the basics of using soft bodies in Blender via this Playlist of tutorials on my Sci Fi Animator channel. If I had a really fast computer, I’d be using soft bodies all of the time!
