    Give the object a compositing tag and enable an object ID in the tag. Then add the object ID to your multipass render.

    Adam, when I do an object ID pass and marry that with the original RGB image, I get a double anti-aliasing (because the Object ID is AA’s and the RGB image is as well) so I get black fringing in the comp.

    I’ve been doing the RGB renders as straight alpha then overiding the alpha in AE with the Object ID. Is this the standard way or is there an easier solution?
