Hi guys,

I am trying to output all the passes (beauty diffuse etc.) with label and coverage in one render. I am outputting the label and coverage through the camera attribute ==> mentalray output shader ==> coverage/label iff method. I can get all the passes I need but when I enabled coverage I got artifact along the geometry edge and high contrast area in the beauty pass etc.. Without coverage the artifacts gone. I can get around it to render coverage separately. But I really want to know what's wrong with this and any way to do it in one render :curious: ?

Thanks for the help!
