Is possible to not render the main image but only passes?

[GIOLETS]

As my title I ask if is possible to render only one or more pass, not the main image.
Probably I've missed something in my setup parameters, because when I render into PV I've always the beauty image.

Hi GIOLETS,
if you enable a pass that needs the main rendering this is not possible, but if you need only several info passes, this is possible by reducing at 1 the sampling of the main kernel. Infact, the info passes have their own sampling setting.

Great tip, it works perfectly!

You can also switch the main kernel to the info channels kernel and render the pass you want this way.
