[300zx_9]

sorry if this is in the wrong section but i recently finished a car and iwanna make some paint materials using vray and i have no idea seeing that i just got my vray so does anyone have any ideas about how i can make a reallistic paint shader and also use a hdri map. I also wanna know how to composite a car onto a background using vray and shadows.
