Invisible to camera?

[ecastillor]

Im making a photomontage, and i need to let the street from the picture to show, but in the render I need a "virtual" street to cast the shadow in the GI to the buildings, but not show on the final render...how do I go About doing this?

if you right click the street object you can click "invisible to camera" that receives gi and bounces lights, reflections without the object being shown.

hope thats what youre looking for.
