After Effects -> Unity Vector Graphics
Every art asset and their animations are generated straight from After Effects via custom Unity framework translating the results of the open source Bodymovin extension to animated sequences of vector shapes.
This custom framework is still early and doesn't utilize every After Effects attribute and property yet, but includes proper keyframe interpolation and currently supports:
Shape fill color
Shape stroke color
Layer rotation (X, Y, Z)
Inspired by the Lottie frameworks that take Bodymovin's data to create animated vector sequences that perfectly mirror After Effects shape animations, and with the help of the new Vector Graphics package, this became much more feasible to implement for Unity.
