Damn, you're right...tongue etc aren't named separately in heirarchy...you would have to make the head mesh invisible through material settings - which would give you that annoying "ghost" in the preview/work pane. I think Appollo Max has a tongue that is a separate parented figure (I'll have to go check of course - checked - yep, teeth and tongue are separate meshes) so that could act as a stand in. AMax's creator must've had the same thoughts about the situation that you have! Cheers
