As tools like Dragonbones, Spine lets you export animations as both sprite atlas and skeleton data (JSON/binary), I'm not sure which format to use when importing to Unity.
I have few concerns:
Will there be any differences between the quality of the animations, when imported as atlas vs skeleton data?
Any other pros and cons, using one over the other?
If I use a sprite atlas, I don't have to depend on a third party runtime though. It is for mobile, so performance is also a concern.
