What is XWear?

This section explains the term "XWear" as used in VRoid Studio's dress-up feature.

 

XWear

XWear is one of the unique data formats for the dress-up feature.

It is used for handling costumes and accessories.

 

Costumes

During auto-fitting, costumes adjust to an avatar's body type by scaling each bone.

*Auto-fitting is enabled for costumes where hips are registered within HumanoidMapComponent as HumanoidBones.

 

Costume files can contain...

• Full costume sets
• Costume parts (e.g. only tops, gloves, or shoes)

 

Accessories 

You can select a target bone for each accessory to follow.
(By default, the bone to follow is set to Null.）

During auto-fitting, the accessory moves to the position of the target bone.

If auto-fitting is performed with the target bone set to Null, the accessory will remain in its initial position.

 

Accessory files can contain...

• Accessories with bones (e.g. a ribbon)
• Accessories without bones (e.g. hats, glasses)

 

XWear files can be created by converting VRChat-compatible costumes and accessories.

The conversion uses VCC and the dress-up feature's editor extension (XWear Package).
