You can control matte properties either on an object level through the VrayObjectProperties node, or on a material level through the special VRayMtlWrapper material. When using V-Ray Progressive Rendering, this option might slow down rendering startup or the overall render speed. Also, if i reboot my machine (with vray registered service) even thought the vrayspawner service says its started, it wont respond when i render, i have to stop it then restart it, then it works.
