The jaw morph target is working fine in character creator 4, but all of the jaw morphs in unreal 5.5 are not working correctly. Other morphs like the smiling or blinking etc are working just fine just the jaw is broken.
I have followed the plug install guide for unreal 5 and every export tip I can find but nothing is working.
For those in the future who are running into this here is your fix:
“This issue is related to one of the options in the Advanced Settings of the Export Settings.
If you check the “Convert Skinned Expression to Morph” option, adjusting the Morph sliders will display the expressions on your character.
When this option is not checked, it will only drive the character’s bones.”
