Hey guys, I thought this was going to be really easy, but now that I'm trying to do it, it seems a bit more difficult (at least to me) than first thought.  I render cars.  And all that I want to do is simply reflect the car into the ground plane.  In essence to create the effect that the car is on a mirrored or shiny surface.  I thought I would just copy the image and then flip it vertically, and then adjust the opacity, etc.  But, I'm realizing that just simply flipping it won't work, unless the car is is situated completely flat along the the horizontal.  If it's in any sort of perspective, this won't work.  Any help you could provide would be appreciated.  Thanks,
