What is VRM?

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

 

VRM

A standard file format.

It handles humanoid characters and avatars.

Within the dress-up feature, VRM files are used as avatars.

 

Data edited within the dress-up feature, including XAvatar, XWear, XRoid, .vroid, and VRM files, can ultimately be exported as a single XAvatar.

The exported XAvatar file can then be uploaded to VRChat.

About VRM0.x and VRM1.0

There are two VRM standards: VRM0.x and VRM1.0.

 

VRM0.x

The original standard, released in 2018. Now deprecated.

VRM0.x files can still be used as avatars within the dress-up feature.

 

VRM 1.0

The new standard, released in 2022.

The updated VRM1.0 standard resolves the limitations and issues of VRM0.x, allowing for more expressive character modeling.

In the dress-up feature, VRM1.0 is supported as an avatar format and for VRM exports.
