mawahahaha  
And here I was trying to be discreet about some of these names. ^^;
My best guess as what EC stands for is "Excrement Channel."  lol  

Translash = Eyelash and/or Eyebrow material which is transmapped.  

I've done some test renders. I used your Awesome render settings and it's taking forever to render. ><  I have my usual Shaders settings and lights rendered, and then I did the VSS shader with my lights. And the results?  Well, my character might be vain because he doesn't want me showing a render of him looking less-than-glamourous. lol. ....  I found issues with VSS's handling of transmaps and displacement I normally never render with displacement, so this is a good catch. Not sure if it is an issue VSS or if the base has wacky displacement.  

My character's face swelled up (dispalcement issues?) and his transmaps got clumpy like bad mascara.  I used a character is inspired by a real person so I have image references of his skintone under various lighting situations (outdoors overcast, florescent, flash, stage, etc.) His color is a pale butterscotch Asian. VSS in it's current default setting altered his skin color.
