Build a VTuber Streaming App

A quick-start guide for building a standalone 3D VTuber streaming app based on VirgoMotionStudioTemplate.

Requirements​

  • Windows PC
  • Unity 2022.3 or later (verified on Unity 6.0.71f1)
  • A VirgoMotion capture environment (the iPhone Capture app + the PC Fusion app)
  • A VirgoMotion license
warning

Without a license configured, motion cannot be received. So, currently, a license is required in practice to build a streaming app. For how to obtain and configure a license, see Configure License. We plan to support other motion capture systems in the future.

note

It goes more smoothly if you have already set up VirgoMotionStudio, entered a license, and verified that it works.

Quick Start​

1. Download the Template​

Get the VirgoMotionStudioTemplate set from Booth.

2. Open the Project in Unity​

Open the downloaded folder from Unity Hub. The first launch takes time to resolve dependencies. On startup, the contents of the Readme asset will be shown in the Inspector.

3. Open the SampleStudio Scene​

Open Assets/Scenes/SampleStudio.unity. You can also open it from the "Open SampleStudio" button on the Readme shown at Unity startup.

warning

Right after the first launch, the VRM file for the sample avatar will fail to import.

This can be resolved by reimporting the affected VRM (right-click and choose Reimport).

Once the reimport completes, the character appears in the Game window.

5. Verify in Play Mode​

Enter Play mode in the Unity editor and verify that motion is reflected on the avatar. alt text

If VirgoMotion has not yet been set up, motion cannot be received. Check the first page of the Remote app and complete the initial setup. Don't forget to enter the license information if you haven't already.

warning

When configuring the license in the Unity Editor, be sure to perform the setup while in Play mode. The buttons related to license setup disappear only while in Play mode.

Once verified, exit Play mode and close the Remote app.

7. Build and Run​

Use File > Build And Run, or the "Build and Run" button in the Readme window, to generate the Studio app.

Run the VirgoMotionStudioTemplate.exe in the folder you selected.
