Hey, thanks for the advice.
I need mine specifically for 'Set Property' so unfortunately
The 2nd piece of advice won't work in this particular case.
I am aware of the use send event too, I am upgrading a project from Unity 4 and all the logic is already done but it didn't use the send event approach as its a large project with 80+ scenes, and remembering and referencing all those FSMs can be impossible to manage.
I was hoping there was another way, but it seems I'm out of options.
Bummer
Thanks for the replies
