Add morphs to your CC4 in UE5 easily and clean up the clothes with the Mesh Morpher Update :

Hi Bassline,
Many Thx,😀
Greetings Robert

Rob . does it happen only when you import the animation as fbx ?

Rob , worx for me : 
Looks like you loose the groom binding , try to rebind the eyelashes and beard !
Some users had the same issue after using Mesh2MH , rebinding solved it.

@bassline - thanks for this!

Trying to work out what is a good workflow as regards multiple character body types and their altered clothing. Will this mesh morpher work if you are using clothes from marvellous designer or is best used for characters with cloths exported out of CC3/4? Also I assume the morphed characters will all still use the same skeleton and animations (even if you meshmorph to make a character taller?)
 

Thanks for the tip! Going to try this right away:)

I had the same issue with some normal human characters I created from a 3D scan.
Eyelashes were a bit off, so I corrected them within MHC. But by doing this I lost the characteristic look of the person.

Yeah , it is a known problem with Mesh2MH (eyes/eyelids) you can solve it with MHC (by fading back to the original) but as you said you will loose the characteristic look you are going for.
Hoping they will fix it within the next updates.
