Active manifestation ?

Hi

For the purpose of a research project, I am trying to use the META Avatar SDK to represent participants in VR and change the different active manifestations. I would like to get sometimes only the head, sometimes head and hands, etc.

I am aware that the documentation says it;s currently not available, but did anyone try to find a way ? Alternatively, I was thinking creating a transparent object that would render above the avatar, like an invisible cape, to hide specific parts of the body, I tried with shaders, cameras, but I haven't managed yet. Anyone would know how to do such a thing ?

Best regards,
Anthony.
