Thanks every body I tried a combination of the answers you gave me to find an answer. I tried a BMP as Azchip suggested (I can save it in Photoshop) but Carrara won't acept it because I'm in a Mac. I've tried PSDs, Picts anf Gifs (no Jpgs) and I still get the same result (the white halo) because of the antialising. And The solution of rendering to a higher resultion and then resizing is no good because I'm doing an animation... and you know it's going to take forever to process
