Streamer Tools for Polyarc Games

Overview

On PC versions of our games we support an additional set of functionality to help make streaming our VR games more comfortable and fun to watch for viewers. Currently we support the following functions:

Spectator Camera

Streaming the first person view in VR is often uncomfortable to watch due to the VR player's head motion looking around world.

The most common way help with this is to add an additional camera that follows a smoothed version of the VR headset position and rotation.

Additionally a statically placed camera may be preferred for the most comfort. The static camera will rotate to follow Quill as she runs around to keep her in view.

The streamer can also grab and move around the static camera to highlight important

VRM Avatar Model

For VTubers or other streamers that prefer to use a 3d Avatar representation, it is possible to load your avatar model into the game using the VRM model format.

Web Panels

It is also possible to spawn web browser sources as movable panels. The main use case for this is to see Twitch or YouTube chat in game while playing

Web Interface Panel

The settings for all of these tools is controlled with a web page which can be launched by pressing Ctrl+L with the game window selected. When this button is pressed you should see a web browser launch and go to the URL http://localhost:1932/index.html.

Twitch Chat Display

For some reason the default twitch chat display link doesn't work in this window. But KapChat appears to work well so I recommend using that. Either use the link generation tool on KapChat or copy this link and past in your channel name:

Troubleshooting

Common Issues:

  • Avatar not loading: Verify the file path is correct and the VRM file exists
  • Web panel not displaying: Check that the URL is accessible and valid
  • Camera mode not changing: Ensure the spectator camera is enabled
