How to "activate" ARKit morph targets in Metahuman Face Mesh

Hi,

I am still trying to export the Face Mesh I get from my assembled Metahuman character (at Content/Metahumans/SKM_NAME_FaceMesh) to have ARKit blendshapes included. This face mesh atm contains the metahuman morph targets/blendshapes (hundreds), but not the ARKit ones.

In the pose asset Content/Metahumans/Common/Face/ARKit/PA_Metahuman_ARKit_mapping I can see ARKit blendshapes as a combination on the Metahuman morph targets. So they are there somehow…

Also, in Content/Metahumans/Common/Face/Face_Archetype_Skeleton I can set which curve is to be a morph target. This list also includes the ARKit blendshape names. I can activate those entries as morph targets but it doesn’t reflect in the face mesh. Do I have to bake it in somehow? Do something else here?

All I want is to include the ARKit blendshapes as correct and fully functioning single morph targets in the final face mesh.

Sorry, I’m a beginner and need to finish this task for a uni side project.

Thank you.
