I am having the same issue. 
BIG Question, When I adjust the eye in Maya or lets say zbrush even thought I don't use it. Do you have to keep it perfectly spherical so basically changing the scale of the eyes only?. I would assume you do but just checking? 

1. I cannot select my eyemesh in Character creator
2. When I bring in a character from Maya the eyeball is not in the right place. 
3. When I try to change the joints, it does nothing
4.Acurig has the Joint in the right position but the  
5. Nothing I do changes the Eye position or anything

There is no telling with importing Blendshapes via  custom created batch. Even knowing most part of it I stumble sometimes with it myself (I only work with Blender though).
Your best bet is to try to verify the sequence in Maya and then try to send your fbx to RL support via ticket.

Hello @4u3ges,
I have batch created expressions & visemes for another humanoid character with fbx file using Maya.
Once comlpeted I tried to import the completed fbx file in character creator same as the steps given in the following tutorial :
https://www.youtube.com/watch?v=A-4lGCu76Sw

It takes some time to load and no data is imported. All sliders are blank.
I tried again , then some data was imported and that was not following the expression 100%.

Please give some solution on this.
TIA

You may re-verify all blend-shapes for the character by running a Motion from animation player in CC - Face Rig > Extended or Standard _Step.
If all is OK, I'd check for latency with Tracking Data Inspector and generally restored all to default if you had some custom profiles.
Otherwise check with some other character to compare.

Hi 4u2ges,
in live face, the character head up/down and head left/right is not consistent. Sometimes it is taking the up or down blend shapes sometimes not!
It is creating a glitch in between the head movement. Same with the jaw movement.
I have filled all the blend shape sliders and are working fine when used without live face.
what may cause this?

@st180492

Thanks, my channel was shut down not so long ago and I had to recreate it: https://www.youtube.com/channel/UCXu7ij7RTcThGh0FwdJaf3w
But I upload most of the videos to vimeo nowadays.

Hello 4u2ges, I just wanted to tell you that I've been following your posts on the forum, and I'm impressed by your knowledge. Your videos are more than helpful. I just wanted to ask if you have a YouTube channel. Thank you once again.

It's probably a skinning issue, or misplaced eyes/head bones.
Generally you should make base Head and Eye Look morphs in CC with respective bones.
If desired, an additional mesh morphing could be added for Eye Look Morphs.

I made this routine for the character straight out of AccuRig.
The only issue in the latest version of CC with Head morphs is,
that after making every Head morph you should restart Face Editor (weird issue and maybe related to my CC installation).
And in Preferences > Face Profile Editor, the setting should be "Remove All"



Here is that character in Live Face

Thank you for the reply.
Yes I tried that. While using motion live I am observing the distortion in eyes and head. For eyes i guess the bones position might be the reason. Head is scaling while head turn and eyes are bulging. In character creator > facial expressions > all slides are working as per added blend shapes except head and eyes. 89% of original size (was 563x553) - Click to enlargehttps://forum.reallusion.com/uploads/images/ac932fc2-cc44-4cfd-8db5-2fb1.jpg
