CC4 Jaw open or V_Open don't work

[butaixianran]

In Blender, Jaw open and Viseme V_Open don't work:

This is how it should be in CC4:

Reason:
In CC4, Facial morph "Jaw Open" and Viseme morph "V_Open" are not just a morph, it is a driver which combines a morph and rotation of Jaw_Root bone.

But after export cc4 character into fbx, this driver is gonna. So, if we import this fbx into blender or any other 3d tool, shape key "Jaw Open" and "V_Open" is no longer a driver, so it won't rotate the Jaw_Root bone, and mouth won't open.

Solution:
In Daz to Blender's bridge addon, it offers 2 kind of solutions for something like this:

• Addon create a new shape key with python expression in it, so this new shape key is actually a driver, which can set multiple shape keys and bone rotations.

• Or, addon panel has a new section for all morphs, all sliders in this section are drivers. User no longer adjusts shape key on body mesh, only use these drivers on addon panel for morphs.

To handle mouth open for CC4, I think this addon need to do something similar, or ask Reallusion converts all those "mouth open" drivers into a real morph when exporting to fbx.

PS: Brow shape keys have the same issue.

Excellent suggestion!

Is this why my mouth isn't opening properly when exported back into CC4 after making edits in blender? Been trying to figure this problem out all day now. I'm new to CC4 is there a fix/solution for this yet? I see something about daz solution but not going roundtrip from CC4>blender>CC4
