bigknockdown Hi! By upgrading I suppose Unity kept both the previous scripts and meta files as well as the new ones, which may I have caused quite a bit of troubles. Indeed I had to rename the ActionButton to HDActionButton because of conflicts with the camera ActionButton and to really separate the two plugins.
In your scene, look for the "roofbtn" game object, and make sure you have the proper HDActionButton script attached with the "Toggle Roof" option:
do the same for the other buttons, and make sure you only have 1 script called ActionButton,
