Hat-less TF2 models

Hey,
In several screenshots with the tf2 characters, they have been without a helmet/hat.

Now, is there anything i missed? a tool, a model-fix or what ? pls tell me, as i am very curious about this.

No, you type in the console while aiming at the TF2 ragdoll “ent_fire !picker setbodygroup #”
the # can be any number, but mostly it’s 2 or 3.
Scout Hatless should be 3 I think
Soldier Hatless should be 3 I think
Engineer should be… 2 I think
Sniper is 2 I think
