updateModel()

I want my NPC to have a player’s accessories, face etc. The problem is sometimes the accessories aren’t placed correctly. image
This script is from a tutorial and I don’t know much about accessory placement. How do I fix the positioning?

Use this to add an Accessory instance to a Humanoid instance of a player’s character.

Nvm, I found a solution. My character didn’t have any attachments so they couldn’t place correctly. I added them and also included Limited_Unique’s suggestion to use AddAccessory.
