i don't know if this problem has been addressed at this forum before, but I looked through some archives and didn't see it, so here it is.

I textured map a plane with some live footage that I am composing with 3d elements. This live footage is a 32 bit iff image, which is cutting out great in maya and on the renders, however, when I turn on the shadows (depth map) instead of casting the shadow of the cutout of the footage, it is casting the shadow of the plane! I have no clue on how to resolve this, could someone please direct me in some direction? Thank you!

You'll have to use raytrace shadows for that because dmap shadows don't care about alpha channels.

Thank you! I tried it, but I still see a faint shadow of the plane over the shadow of the footage, is there any way to adjust that?

Set your shadow attenuation to 0 and that should fix it.
