VRay Matte Issues

[jab]

I'm sure there is something small here I'm missing but I can't seem to find an answer anywhere. I am posting a simple scene in which I want to comp the chairs into the scene later, yet the subtle shadows aren't showing up in my comp. I rendered the chairs into the scene normally to make sure they did in fact exist and to show you the result I am looking for. Why are my shadows dissappearing when I comp the chairs in??

 

My process in going to the VRay props of the ground plane and turning on Matte/ -1/ etc. I've also tried using the VRWrapper material. I've checked and unchecked every combination I can think of here.

 

Any ideas??

be sure to select the shadows and affect alpha options in the vray object properties.

Hey to everyone that viewed this post and maybe is having the same question, I figured my problem out. I feel like an idiot but someone out there may have the same issue. Make sure your ground planes normals are facing the correct direction or that force 2 sided is on. I just shelled my ground to fix the issue but I guess Vray was "seeing" through my polygons and wasnt able to place the shadow matte on it correctly.
