Boils down to a missing animation in a blend state:
![CleanShot 2022-11-14 at 12 26 00@2x](https://user-images.githubusercontent.com/454182/201758919-d0a37458-c0e3-41b2-aaff-56c33fe2a532.png)

We make some assumptions about our Animation Instances always having a backing animation. I've mode those assumptions more robust by including an assert and by having a Blend State always provide an animation, so if one is missing an empty one (with no keyframes) will be used. This maintains edit time and runtime fidelity.
