I followed the tutorial found here: https://forum.reallusion.com/397639/Special-Notice-FAQ-for-CCUnity-AutoSetup-Script and was able to get my Daz character imported from CC3 into Unity.

My new challenge is that with applying an animation, the character has it's mouth hanging open. See attached file "MouthOpenBug"

My animation works with other imported Unity characters but not Gen 3 or 8 - it leaves the mouth open. When I go to configure the CC_Base_JawRoot to another bone - after I click Done & Apply - it reverts back to the CC_Base_JawRoot?! (see image)  When I go to Muscles & Settings, I can use the Open close slide bar under Muscle Group Preview and but when I try to close the mouth using Jaw Close under the Per-Muscle Setting - nothing happens?! (see image). 

I've also tried closing the mouth using blendshapes but it won't close the mouth all the way. 

I'm not able to script in Unity either. Any ideas to resolve?

with appreciation,
