how to make custom morph without using shirt like animatronic morph?

i always wanted to make custom morph, but the youtube tutorial is making morph like shirt/pant/etc.i want making custom morph like animatronic morph, realistic hazmat,filter that show in the gas mask,etc .can someone help me with this one?

First of all, you loop through the model you want the morph to be. Then you weld the morph to the player. Make sure that you weld the model aswell so that it is intact when you weld it to the player. Keep in mind that it should not be anchored or you will be stuck in place.
