We will include a documentation topic for it in the future, thanks for the hint.
There is nothing specific about Spine Mecanim, standard Unity Mecanim rules apply.
Just drag and drop a _SkeletonData
asset to a scene and select SkeletonMecanim
. A Controller
asset with all animations is created for you:
Now drag and drop the animations into the Animator window and set up your Mecanim state machine as you normally would.
