I did it. I finally can rotate it 90 degrees. Welcome to my SUPER AWESOME RIG! This allows you to make your very own character models that you can animate. Super helpful for if you are using several different characters with the same animations, but don't want hundreds of different costumes! The setup is incredibly simple. Click the right side of the screen to progress and the left side to go back. This will teach you how Mr. Rig works! Obviously the knowledge on how to make this work came from @Griffpatch as always.
