I have a scene I have been working on for some time now I can't make an object(any object) invisible to primary rays without making it invisible for secondary rays as well, what's going on, I can't find any overides in my scene, so what could be causing this. Just to be clear I can uncheck the primary ray box in the visibility section of the property editor but the object still shows up in my renders.
Thanks in advance.

P.S. Ahhhhhhhhhhhh.
