Is it possible to allow each camera in a scene to save its own specific environment.....
If i do 4 renders for 4 different photomontages of the same scene , each with a different time or HDR , I need to duplicate the scene four times or keep copies notes.....

I agree. Unfortunately, the only work around I know is to duplicate the scene. Typically, my scenes only contain cameras and environment settings with main model mxs referenced into the scene. That way I only have one model, with various scenes, each with their own environment settings.
