# Adopting 3D VRM VTuber

3D VRM VTuber is a type of character live streaming where the streamer goes live using a fictional character instead of themselves, and uses a fully rigged 3D model in the VRM format to animate and interact with viewers in real time.

Since December 2016, when the Japanese YouTuber Kizuna AI began broadcasting using a virtual character, VTubing has rapidly spread within subculture communities. It has experienced even more significant growth entering the 2020s, and nowadays, it has become a mainstream aspect of the media entertainment market.

Meanwhile, live streaming has become one of the primary platforms for VTubers to interact with their fans. Their VTubing content can easily be found on major global live platforms like Twitch, YouTube, and CHZZK.

However, despite the significant growth of VTubing, it has largely been confined to PC environments. This is because the necessary technologies for VTubing — such as avatar players, facial and motion capture, and avatar streaming — have only been available on PCs.

PRISM Live Studio mobile app has support of a 3D VTuber feature, allowing anyone to easily engage in casual VTubing in a mobile environment.

The PRISM app supports three modes: Screen Live (ScreenCast), Camera Live, and VTuber mode. Select **VTuber** from the list of live types, which you can see in the center of the image on the left below. Here, we’ll use a VRM model-based 3D avatar, so make sure to select a **3D Avatar** from the avatar types.

## Avatar selection <a href="#id-5667" id="id-5667"></a>

You can create their own avatars using VRoidStudio, or download avatars created by others from websites like VRoidHub or Booth to use with the PRISM app’s VTuber feature.

However, the PRISM team has also developed and provided basic 3D avatars to make it easier for you to start VTubing within the app. You can simply choose the avatar you want to use.

## Real-time facial expression capture <a href="#e11d" id="e11d"></a>

The PRISM app’s VTuber feature captures the user’s facial expressions in real-time using the smartphone’s front camera and applies them directly to the avatar. The VTuber feature also supports facial functions that enable avatars to display more natural expressions.

## VRoid Hub Integration <a href="#c3ec" id="c3ec"></a>

​The PRISM app’s VTubing feature supports importing VRM models stored on your mobile device. This allows you to easily bring in and use the same VRM models you’ve previously used in PC environments.

In addition, we’ve integrated the most widely-used VRM model distribution platform, VRoidHub, through a login system to make it easier for you to access and use VRM models.

You can easily download avatars you’ve created and registered on VRoidHub or use avatars made by others, and immediately use them for VTubing in the PRISM app.
