thanks guys for all the help. not sure whether my attempt would as good as some created here. still, thanks alot. ed

thanks for feedback. i'm thinking of rendering a 3d object, say a glowing sphere, with alpha channel and keying it with video files of a person standing in front of a green matte in adobe premiere. the 3d object have to circle around the person. i have tried rendering in photoshop sequence format with the mask box check but it doesnt work with lighting or any glowing effects. any other suggestions?
