New Rear-Projected Shadow Techniques?

Sevey13

Hello. I'm looking to do a render where it's a shadow of a person silhouetted and projected onto a screen. I found an old, old, old tutorial that uses 3Delight. Nothing shows up in the store or online revising this for Iray. Wondering if anyone has a good resource?

Here's the old tutorial: http://docs.daz3d.com/doku.php/artzone/pub/tutorials/dazstudio/studio-lighting04

put character in scene... change all surfaces >base, reflection, glossy etc to Black (for some reason the eyes still had some white that I had to clean up in PS)
render ... took a couple seconds to do the 1kx1k 
save as tif. 
Open in PS
create new layer 
turn in white 
adjust opacity of the new layer which should be above your base 
and then save as jpg 
then render your scene, with nothing where your screen will be save that as a tif 
open in PS copy shadow image put that layer behind your screen (which should be empty) 
save as jpg
---
you can render a "work screen in DS" with a cream fabric say to mimic the material of a pull down shade and then open that in PS shop as use as the layer above the shadow figure adjusting the opacity. 
you might need to play with the vibrance setting to keep color in the overlay layer when it's opagued 
or maybe just put the shadow image over the background layer instead and fade it some
