I am creating images for animation and would like to load them directly into my editor as a string of images.  I am dealing with dozens of images at a time.  

If I create the alpha channel all I can do is use this in my editor a s a mask so that that I can composite the image onto something else - but that is an extra step that does not provide the results you get with an image of a transparent background in a PNG - it's already done for you there!

So, with Esprit I have limitations and I can always use Poser - just trying to handle/match certain lighting situations in  one program.  With the ability to create transparent PNGs in VUE that would be great - but Esprit just doesn't seemt to have this feature. Thanks for all of your suggestions...
