I’m just now realising this cannot be done.
You can either make a UI widget blueprint to customize the font size, but you can only bind the value to some fortnite view models. Which you can’t modify or make your own, so something as simple as settings the string from verse can’t be done. You can add animations and other cool visual stuff like this as well, but it’s pretty useless if you want to show anything aside from the hard coded strings…
Or make the widgets from verse and change the contents to whatever you desire, but be limited to the properties text_block exposes.
I really hope I’m missing something here…
