Hmm. If I just make the blob components larger, the artifacts mostly 
disappear. However, if I scale the whole blob down to compensate, they 
reappear. I am reluctant to scaling my entire scene up at this point - it 
would be an ugly hack. Thanks for the suggestion though.

I don't think AOI can fake SSS except for very simple shapes like spheres, 
cylinders and other completely convex shapes...? Even for those, it would 
work only if the light comes almost from behind. It's the same reason you 
can't use AOI to simulate shading of clouds. It's just not very related.
