I found out during research how to add hats to Roblox avatars in Roblox studio, as I've struggled with it for YEARS. Go to view, and click "CommandBar" at the bottom you'll see "Run a command" type in this command, game:GetService("InsertService"):LoadAsset().Parent = game.Workspace Then in parentheses besides "LoadAsset" add the ID for your hat, then hit Enter. Add your hat to your Roblox Character, and done! It's there on your character forever! I find this way easier than doing the Mesh and Texture thing.
