Running the rig through the ropes, finding bugs, areas of improvements, and animating! The blob spins!
I mostly used this animation to test if I export non-uniform scaling from Maya into UE4, but unfortunately the results came out sheared. Instead I will be scaling the root joint (for now) non-uniformingly in real-time by reading a curve through the Modify Bone anim node in the Animation Blueprint.
I have also been brainstorming what animations I'll need to author for a fun experience, so I got some exciting work ahead!
