New Character Portrait

I’ve seen a lot of people with “404” portraits and was wondering if there’s any ways we could get the same thing.

Anyone know anything on what information is sent during portrait creation? Any ways to block the information or modify it? I know it sends the “position” of our character as well as its “data” (clothes/hair./etc) and renders it server side. So if we were to block or corrupt the data, it’d not render right?

Any info would be appreciated from anyone who has experience on this topic.
