Pretty much every skin on STTT has hitboxes that are normal but with these skins the head is almost 2x the size of the hitbox and it is kinda sad to see how many people abuse this. Gonna ask @Carned for some hitbox models for you all to see.
It really would have helped if you had posted the images before you opened to poll. Right now we're basically going on your word and that's not quite enough. And if it is true, then it is most likely a minor issue as I personally have never encountered problems headshotting either of these models. Unless something has changed I don't see a reason to remove these models. -1 (until further notice)
Link is the worst, ill show them off in a while but they're shit skins even if they did have good hotboxes
As you can see its trash and has no hitbox for half the head. I couldn't find the exact model we use on the servers for MC so, sorry!
To compare, here is example of good hitbox, going from amazing to acceptable, but all are better than Link
Can i use the hitbox renderer while on a SGMOD server or will I be in trouble? wouldnt mind checking the master chief since its posted here but not pictured
I don't think it appears through walls, idk. Maybe try having a person use these skins while you're in spec mode doing it.
