Avatar Entity

I am trying to make an experience, where only the head of a Meta Avatar is displayed.

I have changed the Manifestation Flag, to only be head in Creation Info, with a Third Person Active View. I have toggled Active Manifestation to be Everything and tried it with Head only, without any success.

Could anybody please advise me on what I might be doing wrong, or if this is even possible at the moment? I could envisage it being a later feature.

Thank you
