Tutorial location? Floor shadows of green screened actors

JBaymoreJBaymore Website User Posts: 335 Enthusiast

I seem to remember a tutorial for something I need/want to accomplish.... but can't seem to find it by searching the terms that I'd think of to use.

I have a green screened actor inserted into a scene.  I want to use that "actor" as a 3-d plane  to cast a "real" shadow onto a floor in the scene (video clip background).  I remember that I need to create another 3-d plane that is oriented / lined-up like the floor image layer in the background shot and then that plane gets the actual shadow from a 3-d light I place in the location that duplicates the rest of the lighting in the background shot.  Or something like that.

I cannot find that tutorial.  Anyone have any ideas for me?  Thanks.

best,

.................john
