This is the first time I've added a new skeleton to the project in quite a while. After exporting, I tried to drag the at SkeletonData to the scene. My cursor showed the error "skeleton_SkeletonData is invalid. Cannot create new spine object". Any known issues that would cause this?
I got two warnings in Unity when I exported the project. They're probably the cause, but not sure what I need to do to fix these.
"Could not automatically set the AtlasAsset for "skeleton". you may set it manually
"SkeletonDataAsset for "skeleton" has missing regions. Current Atlases:
none
Missing Regions: sword swipe blue small"
Unity: 5.6.4f1
Spine-Unity: 3.6.xx
Spine Editor: 3.6.48
Found the solution already - easy fix! skeletonData had a button in the inspector that said "attempt re-import". That did the trick.
