Wait, there’s a separate Character node for each piece? That’s really strange, and sounds like a potentially huge performance hole. It should normally be a single Character for the overall model.
I’m still not 100% sure that PupilLeft and PupilRight are the names of the geometries; the egg loader will normally convert these based on the names of the joints they fall under, ignoring the geometry name. So you can’t tell the geometry name from model.ls(). In the egg file, you can see the name of the geometry as the name of the that contains the entries in question.
