problems with compositing

[mascab]

hi,
i've got some problems with compositing...even if i check only "camera visibility", the object is still inlfuenced by light (in my case sun+phisical sky)... why?

[mascab]

none with this problem?
i need the possibility to decide if an object has to be seen by gi or not.
i tried with compositing tag of c4d but it does not work.
