Vray Material Wrapper Reflect Issue

[BadRobotProductions]

I'm sure this has been posted before but is there a solution to get objects above a ground plane to reflect onto the ground plane when using a Vray material wrapper connected to a Vray Light Material (non-emitting..just the camera mapped texture applied to the groundplane)

Matte Surface is selected,
Alpha Contribution is -1
shadows and affect alpha are on and the reflection amt is 1

Looks like the best way to do it so far is to just create and override and break things out...though it seems the backplate light material won't work at all for reflectance purposes.
