Now when I was working on this animatronic I was genuanly curious on how you can model a vest for the animatronics because on youtube there are these fnaf modelers that include a vest for their specific animatronic model they are working on. When I figured it out how to model a vest it was simple and easy to understand.

For those who are curious to know how to model a vest here let me explain.

Basically when modeling a character or animatronic model's torso, you can copy the torso body that you made and edit the front section of the body and once you are in edit mode remove the front section of the body and then once that is done add a thickness modifier and you are done

Hopefully this will helps

Anyways enjoy.
