fading screen to start lvl

hello i have a main menu that takes you to a loading screen. afteer that the first lvl begins but how do i make a black fading screen ?

Create a black object in the UI layer that covers the entire screen.
Start alpha at 0 and when you want to fade, use an Ease behavior From 0 to 100.

You can see this in NYCTOPHOBIA, go to the UI layer and you will see a “Fade-2” object:
