Hi.
The problem is in that you’ve put the overlay opacity command after the background title. You write in the overlay in the area, it’s location and layer after the the background but any other overlay command - such as opacity changes has to be written seperately into the script.
EXT. DONUT SHOP - DAY with DONUT SHOP at layer 2 <—background and overlay’s are placed. &overlay DONUT SHOP TWO opacity 0.5 in 0 <— opacity of the overlay is changed to see-through instantly.
