Need help on a loading screen
So I was trying to make a loading screen sort of like the game Super Golf. The loading screen will be a black and white image on the screen that has color fade into it from the bottom. (It doesn’t have to fade but at least have color come into it from the bottom) I have been searching YouTube, searching the internet, and searching the Dev Forums and I couldn’t come up with anything! Please if you know anyway on how I can make this loading screen please reply!
The image I am working with : Black and white, color version
