I've experimented with the EZ Blinn Node's Reflectivity value. The first image is the normal EZ Skin shader I've been using. It's value is .5. With a rim light set at 120%, you can see the blown highlights. These remain in the right shoulder through all of the images, as I didn't mess with values for the rest of her skin.

The second image has the Reflectivity value set at .25.

The third image has the Reflectivity value set at .1

The fourth image has the Reflectivity value set at .05.

This deals with the highlights being blown out, but her skin starts looking a bit flat, the lower I go. This was not an issue using Superfly in P12.
