I would like to add a movie to the projection screen that comes with Carrara(it's in the office folder on the content cd). I have chosen a movie but keep getting a null pointer error. I could also use some advice as to which shader chanel to use for this effect. I want it to like like a movie being projected on a screen. I have the carrera bible and the owners manual but bith are a little light on rotoscoping. Thanks Juggler
