Making Matte Shadow Work

I have searched for this but the answers seem somewhat inconclusive.

I have a teapot and I want to render the teapot with a cast shadow on a ground plane.

I have created a VRayPlane object and set it’s VRay Properties to be:

Matte object
Shadows
Affect Alpha

If I do this, the plane object shows in the alpha and any shadow action is obscurred. If I set Alpha contribution to -1… then there is no alpha for the plane object including no shadows.

I am sure I’m missing something… what is it?

Thanks!

Ahhh… nevermind. It is working (just hadn’t gone far enough to the frame where shadows were visible on the plane).

Thanks anyway!
