The top image is what Garrick's hair looks like when rendered in Superfly right out of the runtime. I've included the hair shader in the second image. Color Math 2 and Anisotropic 2 are problematic. But I've applied the updated hair shader from EZ Skin in the third image, which doesn't look any different than the second one. Immediately, Garrick's hair disappears. When rendered, it looks like the image on the bottom.

Good grief!

I can't imagine how frustrating this would be for a beginner!
