How can I assing the light to effect only on one object?

I do not want that light to him my floor.
Only the character. What can I do? Render 2 passes?
I cannot find a setting in lights for this…

try using a disklight, and set a small cone value in that property.

Hey thanks, an idea worth trying. But does not help with the reflections from the floor:

Rob Bryant had a trick on this on his show.

The lights Property / Specular Multiplier set to 0 kills the reflections on floor!
Light Shaping / Focus value is doing this too but in my case the light in characters face was cranked down to almost invisible…

Thank Rob!!

In use. Specular Multiplier set to 0. Voila!
