  Right. As you say, Anth, at IC=100 there is no caching. And that is the actual bug - the cache is not consulted for a reflection. Turning off caching doesn't show the bug is gone - it demonstrates it.

  IC=100 in the render settings dialog does not turn off caching for IDL. (the D3D dialog might, I never use it so I don't know) It does turn off caching for AO, but not IDL. IDL without caching is either very slow or very noisy, depending on how much samples you use.

If you really want to see it without any caching, type this into the Python console:

poser.Scene().CurrentFireFlyOptions().SetGIMaxError(0)
poser.Scene().CurrentFireFlyOptions().SetGINumSamples(32)

Also, keep in mind that shiny spheres on ground planes are test cases for shiny spheres on ground planes. That test case obviously has issues, but that doesn't mean that figures in front of mirrors in rooms will.
