So, unity’s default button has curved corners on their buttons. When I put some texture in the GUI skin
the buttons were no longer curved, yet it seemed they were trying to curve. Do my artists need to make the texture
curved to get that effect or is that something I can do on my side?
Not sure what you mean by “trying to curve”…
Your button texture will still be rectangular, but you can have “curves” by using transparent pixels where there should be no button.
