Reflections on standard mats. vs. Vray mats. not showing!

Hello,

I have a standard material floor, that I want to be slightly reflective. But the weird thing is that its only reflecting other standard material objects, and not my Vray materials. Its like they are being completely ignored. Is there and option to change this?

Are you using vraymap or raytrace? raytrace is not compatible with V-Ray.
