Hello !
I'd like to make an object, and that the background of the scene id
transparent, that is to say, the output file is a png file, and i'd like
the background to be really transparent, in the final picture.
I considered using a specific background color, that I would have turned
transparent, but miror shows a bit this color, and it becomes ugly... Plus,
I'd want transparent objects (filter or transmit) to be partly transparent
in the final image...

Is it possible ?

  Use the command-line parameter +ua

This way, wherever you have the background, it will show as fully transparent. 
Wherever you reach the background trough transparency, you will have partial 
transparency to whatever is behind your image.
But remember that the colour you pick for the background will show in 
reflections that would have shown the background.
