Thank you for sharing this link.
It actually took me many attempts to find the one method that would finally allow me to enjoy a rather clean installation.
I kept making backups of the project during the construction phase, each archive being a validation of project.
I knew the hard part would be in making Playmaker uGUI work without throwing errors, and having the main scene working without so many actions losing their scripts.
Thus far I keep hitting a wall because after installing the full uGUIproxy package found in the UI Master ... Ecosystem/ folder, I get 26 errors all related to LogFullPathToAction.
Such as:
Assets/PlayMaker ArrayMaker/Addons/Custom/Table/Actions/ArrayTableGetItem.cs(92,62): error CS0117: 'PlayMakerUtils' does not contain a definition for 'LogFullPathToAction'
Once this will be cleared, I'll move to the next and equally problematic case of avoiding certain actions becoming "missing actions". It took me a while to find the right parameters for some of them and I just can't afford having to rebuild and retune entire parts of the project.
I did all of this in order to have a ideally perfect setup for my scene to precisely
not to have to look for scripts, always working with an empty scene first.
