I am on my project, but find it hard to understand what I'm missing from those few animation and rigging tutorials.
I have an FBX I modelled and rigged from blender... Or I could just take a model from Mixamo or other resources.
Is it possible to have loosely coupled .anim files which could be mix-matched at runtime with different FBXs?
It seems the Animator Controller can reference each .anim file independently if necessary, so I guess we can make one animation per fbx and split anim files in Unity project explorer... There must be a better way, right?
