I actually have a Muggle at my theatre that asked me how to make pictures fade in and out for a kids program that she’s building. There’s only like 8 pics so I said, “import all the pictures and set the surface to our projector. Then set the opacity to 0.”
Put em all into a group and set them all to auto continue. (Except the last one)
Create 2 fades for each video. One with the opacity set to 0 and the other to 100.
Put all of these into the group with the pictures to keep them out of the way.
Then outside that group I pair the fades with the first on auto continue.
So if I am currently seeing picture 1 on the projector and I wanna fade to picture 6.
I make a copy of the 0 opacity picture 1 and the 100% opacity for picture 6. Then set the first one to auto continue.
I’ll post a picture later if you like, but it works like a charm, and since pics are all low ish quality the computer has no prob running all at 0 percent opacity for the duration of the show.
