Need Help Setting Up In-Experience Avatar Creation (Accessories & Hair Editing)

Hello! I’m looking for someone familiar with in-experience avatar creation, especially for accessories and hair.

I’ve been trying to use the roblox example, but I’m struggling to understand how it works. I can’t figure out how to properly set everything up or how to add my own hair and make it editable.

Does anyone have a simple example of this system, or could explain how to set it up correctly?
