Hi all, Id like to offer a trick i thought up when i needed to add a womans reflection into a mirror
Simply set up a camera where the reflector is and, using a, the snip tool of windows 7, or export the actual snap shot as a jpg. take it into photoshop gimp or any other image editing software, and rotate, scale, flip etc. as needed to get it into the right position. then just add it as a texture.
im sure this is already known, but just thought id try to add to the community.
Hope this helps
