I have a scene in which there is an object that I want to use as a indirect light source. I've overridden the ambient color of this object's material to serve me as a light with its final gather cast.
My question is how can I isolate an object so that only it's illuminated by the final gather cast the other object that serves as indirect light. I think It's difficult to explain it with words only so here's a simple render for demonstration.

In this scene I turned on Final Gathering. I want the white object to cast its lighting only for instance to the red box. I don't want the green cylinder & the yellow cone to receive any illumination from the white plane.
Is there a way to do this --without setting the Irradiance Color of both the cone's & the cylinder's materials to black-- Because I want other color casts on them lately.
