How are Metahuman's animated face masks triggered through animation?

[Bonne]

Hi all,

First time posting, sorry if this has been asked before, but haven’t been able to find the answer so far.

Can anyone tell me how the parameters to blend the animated masks of the Metahuman face material are being triggered ?

The screenshot is from within one of the material functions driving the masks, the parameters on the left seems to be referencing specific curves. I’ve found these curves in the mh_arkit_mapping_pose but I can’t tell how it’s connecting up to the parameters.

Have been trying to find the connection for a while now, assuming it would be triggered somewhere in the facial control BP or animation BP, but i can’t find the missing link.

anyone who knows the answer to this ?

Thanks in advance!

The materials and the animations share the same curves. You can get more information here,
