FBX Character export into Motionbuilder?

Virtual Media

I've got a Daz Character I need to export into Motionbuilder with .fbx. The export works nearly flawless however when I add the Character face to the Model and add expressions the Character looses most of the customization.

If I disable the Character face and click in the original timeline the character will revert back to my customized character.

I've tried saving poses in MB and tried to tweak the character back to the one I designed in Daz 4.5 but many of the custom shapes didn't export through in .fbx.

Any help would GREATLY be appreciated.

Happy Holidays!
