I was wondering how/if it is possible to have a drop shadow effect of one object onto another, but when rendered with an alpha channel not visible over the background (IE, no bleed off over top the layers). I am thinking along the lines of something like light linking in a 3d program.

I have made two objects and applied the drop shadow to it, would making actual lights be the only option or is there more to the drop shadow effect than meets the eye?
Thanks!

I would think if you set up your objects.. 2 of them... get the shadow casting properly regardless of where it lands to begin with. duplicate both objects with shadows turned OFF on those. Pre comp both of them.
drag the precomp into the shadowed pre comp and use it in the "stencil alpha' mode.... that will clip\limit your shadow to just those 2 layers... actually really quick to do... not so quick to type... :)

If you do this with a light, 3D layers and NO background, you can render it and it should look as you want it to.
