A Guide to Using & Animating OVERLAYS :rose:

Also I believe this thread should be in the directing helps and tips category. Check out the Official Tutorial/How-To for the Forums (V2) :sunflower:

So you add the on the line with the background so
BACKGROUND with overlay
You then can scale it in preview

I add it on the same line as the background?

Yeah so the background you want with the overlay you want on the same line so
BACKGROUND with overlay

If you check out the thread I linked and go over it, it will explain everything :heart:
