I appreciate your information.  But you know, somebody's got to try to do it their way.  I have a few cyclorama backgrounds and some scene backgrounds, but they seem square to the back.   I want to move multiple  planes to where I want in relation to the character and props (lights and shadows please).  I have some jpg backgrounds that work with the edit backgrounds, but but they are not as  flexible.  I will have to think about it more...
  Thank you for your help.
