A way to render with transparent bg but...

…but with light rays bumping on the non-rendered objects.

Im trying to render glossy item animation as png series with transparent bg, but i want it to reflect the non-rendered staff, cause i will be using the pngs in flash animation on the rest of the scene saved as single image. Is there a way to do it easily?

Thanks a lot in advance!
Regards.

edit:
Sorry, i thought it will be harder so i asked before trying. Its enough to just disable ray visibility “camera” and it works just as i wanted :slight_smile:
