Hello, the teeth and tongue are static in unreal engine when attempting to use blendshapes/morphsliders in Unreal engine with FKcontrol. See two images below for discrepancy between UE5 and CC4. Any help would be greatly appreciated. 76% of original size (was 664x19) - Click to enlarge76% of original size (was 664x19) - Click to enlarge

CC Characters jaw , tongue and eyes are bone driven in UE5 , so you have to animate the bones together with the blendshapes/morphs in the FKRig ... or better use LiveLink.

Thank you for replying!
