# Head Items

{% hint style="info" %}

## Difficulty: <mark style="color:green;">Very Easy</mark>

{% endhint %}

Given that head items almost always need to be weighted only to the head, this is the simplest type of cosmetic item to add, and is very beginner-friendly.

### Hair & Hat Interactions

When modeling a head item, you may want to take a peek at the supplied hair models within the rigging guide. Given that hair and hats both need to fit on a player's head, **hair needs to change its shape depending on the hat.**

As such, **hairstyles have four possible shape keys: hats, helmets, masks, and hoods**. For helmets that cover the entire head, like hardsuit helmets, the hair may be hidden entirely.

When designing a head item, you may want to enable the desired hair shape key and design around it.

### Rigging Head Items

The majority of head items (aside from things like hoods or hats with dangly bits) can be weighted entirely to the head bone. To do this, make sure the hat is parented to the armature with empty vertex groups, then in edit mode, **select all vertices and assign 1.000 weight in the** <img src="https://lh4.googleusercontent.com/B_2prMF26aDM_DAWhgtu-eWOiIfNp5cZbmhi-dc7aoTnas4x0SusOmfomLOREm-DGUNHWBT-jf4Eii_lGp4og8STeSIUXE4aNnnxQMrSqHRMv5QtBifDiW5ecC0jR1dl-BQOI3HlS6C_ek_5JJRLf04" alt="" data-size="line"> **tab.**

After you're done, consider whether your hat needs a held variant based on the type of head item you created.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ss3d.gitbook.io/art-guide/3d/rigging/head-items.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
