I am trying to light a wall and a tabletop separately using 2 lights with different light pass ids. I'm getting light from the light that illuminates the wall bouncing off the wall and illuminating the tabletop.

Is there a way to stop this happening? I thought the path tracer would understand that the bounced light is still coming from the wall light and therefore not allow it to illuminate the table?

Please post some screenshots, and/or an example scene, thanks.

ciao,
