I'm currently using Unity 5.3.1f1. When I try to enable tk2d using the references, I get the following error:
PlayerSettings Validation: Requested build target group (0) doesn't exist; #define symbols for scripting won't be added.
UnityEditor.PlayerSettings:SetScriptingDefineSymbolsForGroup(BuildTargetGroup, String)
SpineEditorUtilities:EnableTK2D() (at Assets/spine-unity/Editor/SpineEditorUtilities.cs:1146)
SpineEditorUtilities😛referencesGUI() (at Assets/spine-unity/Editor/SpineEditorUtilities.cs:1125)
UnityEditor.HostView😮nGUI()
With this, the json files in spine are not detected to prompt for a new SkeletonDataAsset. Any suggestions for this? Thank you very much. 🙂
