The knowledge base alludes to MegaPOV having some blurred reflection 
capability, though I cannot find it in the MegaPOV documentation.  But 
MegaPOV development terminated long before UberPOV was released.

Since development of UberPOV has wound down, I've found myself reverting 
to RC3Metal from the Object Collection, which works with standard 
POV-Ray.  What seems to work best for me with RC3Metal is to do a bunch 
of EXR renders with different seeds in an animation loop, then read them 
back as image maps and average them in a pigment_map.  To save time, I 
save the photons for the first 3 to 5 frames, then reuse them round 
robin for the remaining frames.  If there are no mutually reflecting 
surfaces, I just use a single render with a high sample count.

Overall, UberPOV does a better job than RC3Metal, though, especially 
with specular highlights.
