meant to post this yesterday - the image on the right was finished, and tweaked in PS, I'm just using it as a for-instance. I opened the file in Bryce again, moved a flower downwards, then plop-rendered just that area. Then I can cut/paste that little square on to the finished render in post-work. I see that karineq mentioned that he/she knows how to do that already, I'm posting it more for new users who might be reading this thread - I didn't know what the hell plop render was when people talked about it lol.
