Getting a transparent background using the screen snapshot works fine, but I would like to have a rendered image. I have tried adding the +UA tag (which I believe should render the alpha channel as transparent) as a povray command line option so that my input looks like such: povray +A +J0 +Q9 +UA +H2400 +W2400 input_file.pov Yet this still does not give me a transparent background. When generating povray input files, does ccp4mg output the background as the alpha channel or do I need to go about this a different way? Thanks, Ray -- Raymond W.
