How about how to make a good looking umg ui. All the tutorials that I find usually just have “and you drag and drop widget and TA DA, you have a button!”
Show us how to set more appealing menus with customizing the default UMG widget, using a 9-slice image (which is mysteriously not covered in any form other than mentionings that it exists), animating buttons into view, pie menus, command rose (like in battlefield for PC) and anything else you can think of.
I really don’t care about setting up the of the button. Tutorials on setting up those functions are all over the place. Just focus on making it look pretty.
