Hello, are you rendering to an avi file, or to sequential images? If you are rendering to an avi, set the background color of your Poser scene to black, then render the avi. Then set the foreground color to white, and change the document display setting to "sillouette" and re-render to a new avi, with the render settings to current display. Check the anti-alias box. This will give you a new black and white mask as an .avi. If you are compositing in premiere, you can just set the transparency of the original avi to alpha channel, since Poser saves the alpha with the avi. Or you could use the mask avi as a track matte. This should kill your crispy mask edges. If you are rendering to separate frames, you can use tif files as numbered stills since the tif format retains the alpha info as well. Hope this helps. I have done this countless times. If you have any specific questions, feel free to email me. Co(V)(V)union communion@rocketmail.com
