Alpha Image Map with Shadow

OK…I have a problem here:

That image is a plane with an alpha image mapped to it. I want the shadow to outline the alpha image, not the plane.

Can Blender do this? I tried the same thing in C4D and Anim8or and got it to work fine.

THanks for your help!
(BTW: Running Blender 2.33a)

The Producer

activate the TraShadows button in the materials window of the object that is recieving the shadow. That should do it :slight_smile: .

and press the RAY button in the render buttons to enable raytracing, and use raytraced shadows for your lamp (settings in lamp buttons)
