lesbentley,

I hadn't noticed that before, but yes that is a significant difference. I couldn't, however,  find a 'BG Picture' node. Can you tell me how you get to it ?

thanks,
Andrew

PS I noticed that there is a fleeting reference to the 'BG Picture' and the 'BG Movie' nodes in the Poser manual, but it didn't enlighten me on where to find it.
