If you already set a facial scene and want to add an object typically the eylashes, you need to reset the scene manually.

If you didn't set the group, this need to be set manually also.

Mimic this setup :

Delete the blendShape nodes, and recreate them with this rules :

 The *BSuser come from the modeler scene.

Additionnaly, make sure all infos in FCL_tags fit to your scene. If you set the facial with intermediate group, this should be ok. If not, you would have to adapt some infos

Also, make sure the group in the final BASE scene fit.
