Matte/Shadow/Reflection material for VRay?

[Streetwise]

I was watching this tutorial on how to do camera matching for compositing 3D objects into a 2D scene. In it, he references the use of Mental Ray's Matte/Shadow/Reflection material for receiving shadows. Is there anything similar to that in the V-Ray world? Quite simply, I've been tasked with adding picture frames to a wall where the light is provided by fluorescent ceiling fixtures. I suppose I could add the shadowing via photoshop, but wondered if there's a better way to do it in the absence of the MR material?

Thanks.

Just select the plane you want to receive shadow and go to vray properties - matte shadow check...and that should do it. You can also check alpha -1, and affect alpha it will write the shadow into alpha for compositing.
