Hi. I'm trying to render out to a transparent background. I selected the render alpha channel, and tried all of the options. I even tried it as a gif, but the box to select transparency to white or black was not enabled. I am very new to Carrara and don;t understand what i am doing wrong. I plan to composite with Adobe Photoshop Elements 3. I'm running a G5 (non intel) mac with 2 gigs ram. Please help. Thanks. David
