Hey there!

I have some GUI i’m making for my game and I make some GUI I’m pretty happy with. However, when I test it on the actual game from the website it makes my GUI slightly stretched compared to studio. I have all sizes and positions set to Scale.

Using UI Aspect ration constraints seem to fix the problem
