slide projector scenario
I am setting up a scene where there is a slide projector show taking place and then a man interrupts it to say something.
I have the man shot on green screen and the “slide show” set up. What I’m trying to do is a realistic “projected image” on the man’s body of the BG slide. Any ideas about how to accomplish this? Thanks!

Any layer can be set to have light transmission instead of a shadow. Place a copy of the slide show layer in front of a light that shines on the guy’s layer. This isn’t very easy to do but it’s a ton of fun. You can look around here and other AE forums that offer tutorials for stained glass effects.

You can also use the soft light transfer mode.
To get the image to distort over his body, try using his layer as a displacement map for the slide layer. It won’t be correct (since the displacement would be based on his lights/darks, not his 3D contour), but it might do the trick. Consider though, that if he’s seen from the projector’s exact POV, there would be no displacement. You know what I mean?

Maybe I’m missing something. Why not just get a camera, a slide projector and a guy and leave out all that keying, light transmission, stained glass effect, displacement based on luma junk?

Thanks for all the advice, guys. Yeah Ian, if I had it to do over again, I would probably actually project the image onto the guy and capture the whole thing live. But, at the time, there were too many inherent timing problems to capture it live. Plus, I would also have the added headache of getting slides made (remember, it should look like a slide projector, not a video projector).
I didn’t care so much about the displacement of the image on his body, as I just blurred it very slightly. The soft light xfer mode gave me some desired results, but even with opacity on this layer set to 10%-20%, I was getting to many unwanted problems with how it interacted with the keyed layer. I tried adding an alpha matte in addition to the soft light, but it just got stranger…

I just did this today. Put the slide projector precomp in front of a light that represented the projector lamp. Properties set to transmission 100%. The slide image sprayed beautifully across the elements in the foreground.
I don’t see a problem nor do I see any need for a transfer mode as there is another light in the scene.
