Not sure, but JPGS don't render with an Alpha channel. But I would be curious to see if it was just a TIFF issue. I suspect it has something to do with it drawing it on screen. (When you render an AVI, as you know, it does not show you what it is rendering.) Also, on the QT, write a quick email to Curious Labs requesting QT abilities in a future release. I have several times over the months/years ... the more people the better. And the real advantage to doing it in Poser is of course so you will have an alpha channel, converting it to a QT4 won't work. -Tim
