Just a bit of my 2 cents here. Just to stress what's already been said. Try to use a background color in Poser similar to what the end composite background will be. This just helps if some of the outlining pixels get in there (Alpha channels aren't perfect, but Poser does a very good job). NOTE: If you have other items behind/in front of your Poser figure (or object you're trying to render) these too will become part of the alpha channel. I have often done a Poser render with a "backdrop" behind the figure and when you look at the alpha channel it is completely white because it took into concideration the backdrop. So only place figures/objects in the Poser render that you want "cut-out" or masked. Yes! Save as a PSD (PhotoShop uncompressed) and Poser automatically saves an Alpha channel. And by "Condense"ing the selection in PhotoShop by 1 pixel will get rid on many of the outlining artifacts that may interfere with the composite. But you can further eliminate these pixels with a "Quick Mask" and get your hands dirty and paint out the unwanted pixels, and then resave this new selection to the Alpha/Channel. James
