Jada 8.1

OK, what am I doing wrong. Jada 8.1 shows up in renders and Iray previews without any skin color. I went in and clicked normal maps no luck. Then all maps still no luck. This is the first time I've seen this problem. Any ideas what I've got wrong?

which version of DS do you use? the new shader used by G8.1 requires DS 4.15
I use DS 4.15.
I just went in and added a different skin material and it worked. But I should be able to use the models actual skin. Would like to figure out what's going on.
The skin loaded for me, so I'm not sure.
Ive had no issues loading the skin either. Maybe uninstall and reinstall? Something might have glitched.
