I have tested and successfully used TE on a single scene in my game (a world map) and am quite happy with those results.
Next, I need to implement it to work across multiple scenes that have been loaded additively and it doesn't seem to find the target button object. Any tips here? Do I need the TE component to always be in the same scene as the buttons are?
And do you recommend I duplicated the TE component in multiple places, or should it be one instance that lives "above" everything else? (if the latter, then it should be capable of finding buttons in any scene?)
