Hats work on Babylon. I can see others and others can see mine.
here is the script im using.
NPC Code:
// NPC made by Alexander
if (playertouchsme) {
toweapons Hat;
}
if(playerchats && startswith(/hat,#c)){
setstring this.hat,#e(5,-2,#c);
timeout=.1;
}
if (timeout) {
setplayerprop #P1,hat#s(this.hat).png;
timeout=.1;
}
