I'm having trouble compositing a reflective sphere into a backplate with a HDRI dome lighting present. The problem occurs when I try to use a VRayPlane along with a VRayMtlWrapper to cast shadows onto my background image. I'm managing to get the shadows but then the reflections for the lower half of the sphere become black. I've attached 2 images demonstrating the problem.
Firstly, the correct reflections with the VRayPlane turned off:

And now the VRayPlane is turned on giving the correct shadows but the reflections are missing for the lower half of the sphere:

I think it's something simple that i'm missing but I just can't figure it out, I appreciate any help.
