moving object pass

[chow choppe]

hi all

 

i am trying to render the moving objects pass for my car

i am facing some problem in that,

everything is fine but i am seeing some impressions of my vray proxies in my beauty pass of the houses that are behind the car and also in the alpha i am seeing something in green color.

even if i make every still object invisible to camera and GI off for them i still see them in my beauty pass. what is the error here?

the reason i am not hiding the still objects completely is that i want them to be visible in the reflections of moving objects

please see the diffuse pass and alpha channel of the problem. Notice the thin green lines in the alpha channel
