I *guarantee* you it did, beyond any doubt.

The blotches also tell me that you're using a version of POV prior to
3.7.0.beta.29-rad1 (or a derivative; given that you mention HDR, I reckon it's
MegaPOV 1.2.1)

Your scene's setting is the role model for the infamous POV 3.6 (and earlier)
"black splotchy artifacts" radiosity bug: An abundance of reflective stuff with
an abundance of interreflection. With this setting, you're almost *inevitably*
to contract the "black pox".

There's just one thing to rule them all, find them, bring them all, and in the
brightness bind them: Crank up max_trace_level a really good deal. All other
resistance is futile.

(Or use the current POV 3.7 beta of course.)
