My character is without a head...

I’m been trying to get my player in thirdperson for a while now, and i’ve finally accomplished it, without having cheats on (yay me), but he doesn’t have a head, or arms…

I’m guessing it’s because he isn’t supposed to be seen from this view or whatever.

Anyway, i’m looking for either a solution or an alternative.

Thanks in advance.

PS it’s in a gamemode i’m making.
