Yesterday, I bought a new character set for V4 named Catia Evangaline. I've applied her skin shaders, head morphs, and eyebrow pose, but her eyebrows don't appear anywhere near as well defined as they do in the vendoer's promotional stills in test renders. Here's a link to one of those renders:

I've already contacted the vendor for help, but thought I'd post a message here while I wait for them.

Any suggestions?
