Models with more than one expression

[ElmerFuddFan]

Do I open the original and unedited model in there? Also what are the names of the meshes I delete and the ones I join into one?

Yeah, the original .fbx. It starts out small in blender so click on the empty at the top "elmer_fudd_cupid_1" and scale in the 3D view by pressing S and moving the mouse away from the center.
The names of the meshes depend on what face you want. Let's say I want Elmer's scared face, then I would delete:
elmer_cupid_head_sad
elmer_cupid_head_angry_smile
elmer_cupid_head_default
And join:
elmer_cupid_head_scared
elmer_cupid_1_body
elmer_cupid_1_quiver
elmer_cupid_1_wings

This was the... "result". Not upright and missing pupils. I hate 3D modeling so much :'(
