Eyes and jaw are usually bone-rigged. Daz is that way too.

Does UE4 use a complete face rig?

The face bones are there. I'm pretty sure they are being used i.e. when the jaw opens, bones for the lips and cheeks are probably necessary because blend shapes won't work at that moment. 

But regardless, I see them, and I want them! :D
The rest of the rig makes it into Maya, working and animatable, so please apply the same transfer to the face bones :)
Thanks!

apparently I was partially correct in saying the G6 characters don't use facial bones. It makes sense that they would not change the skeleton, there's no real need to.

That's a good question :)  I forgot where I was in the process. Looks like I had reimported the FBX file. The face bones show up in 3DX, but I don't know if they work.  I've applied MotionPlus created with Puppet Tool and Face Key, but from what I understand that's all blend shapes now.

The face bones show up in Maya as empty nodes with no joints and no weighting. I've shown the entire process to Reallusion support --- shown that it works for G5, but not for CC. So far (since Thursday I think?) they don't have an answer for me.

How do you convert to non-standard a CC? Mine is grey out... May because you've the pipeline version?

YES... this would be fantastic. Or a plugin to export MOTIONPLUS files from MAYA to iCLONE.
Right now I will take a patch/plugin to get 3DX PIPELINE to export a CC rig WITH Face Bones to FBX as promised. :D

I'm curious how exporting MotionPlus animation files would help the situation of exporting the face bones along with the rest of the rig. Can you tell me more?

How about a Plugin for Motion builder that would export MOTIONPLUS files for ICLONE ?
Then the user could load both body and facial motions into Iclone !

Well that seems like a good one for me to be wrong about! :blush: In that case, make sure you are exporting "Motion Plus" animation files.

I'm still on 3DX5, so didn't double check.

If I convert her to a non-standard you can clearly see the face bones.
