Animations for people models don’t work though they worked in the previous versions of Unity (4.x) (Mecanim, Humanoid). Simple animations like rotation and shifting objects work. Legacy animations also work.
I got the error that can be connected with the not working animations:
Invalid editor window UnityEditor.Graphs.AnimatorControllerTool
UnityEditor.EditorApplicationLayout:FinalizePlaymodeLayout()
And I got the error:
Failed to destroy editor windows: #1
AnimatorControllerTool
UnityEditor.WindowLayout:LoadWindowLayout(String, Boolean)
