In Cararra, is there a way to save a foreground image as a layer which can then be superimposed over a background image?

If I get too much detail, too many objects, into a scene it becomes unwieldy.  Rendering the background and then the foreground seems a good workaround.

A jpg with no background saves with a black background.  The true transparency of a layer is needed for a realistic overlay.
