I may not say bagginsbill is the man to see first about SSS though.  If it were to come down to free stuff he's The Man, but face_off's HyperRealV3(And other) python scripts are top end.  They're like $25, but are well worth it.  I'll post some before/after shots tomorrow or so, you'l be surprised how much is contributed by his script alone!

BTW - SSS only really works very well with medium complexions.  Just keep that in mind when your thinking of going for that special realism.
