I wanted to use Attachments to attach decorative items/etc to tools/weapons. I discovered that unfortunately Attachments don’t work with Accessories unless they’re in a character – specifically, they require a part named “HumanoidRootPart” and “Head”. Here is the difference between using Accessories+Attachments in a character vs non-character:
Accessories shouldn’t require a character (HRP + Head) to work properly. They have many uses outside of characters.
