I need help with fading overlays

Hey there! :wave: Thank you for giving up your time to respond to me!
I need help with fading in and out with overlays!
I have searched it up on the forums and I have followed their steps but it keeps saying it’s incorrect.
Here is my code :smiling_face_with_three_hearts:
INT.BACKROUND.INTRO with INT.INTRO.OVERLAY
@overlay INT.INTRO.OVERLAY opacity 1 in 2

It says the backround put in doesn’t exist and the @overlay INT.INTRO.OVERLAY opacity 1 in 2
is ‘invalid’

Hi!

I’ll try something different, not putting it with background
INT.BACKROUND.INTRO
@cut to zone 1/2/3 (if there is more zone than 1)
@overlay INT.INTRO.OVERLAY create
@overlay INT.INTRO.OVERLAY shifts to xyz (you need to set the placement ofc)
@overlay INT.INTRO.OVERLAY scales to 1.000 1.000 (you need to scale overlay too)
@overlay INT.INTRO.OVERLAY opacity 1 in 2

Do check if your background and overlay name are the same as the names you’d uploaded as in the catalog. Are they misspelled?
