The config.json file is created when you configure VirtualCast on the settings screen.
The settings screen is displayed when you press the gear icon at the upper left of the title screen.
The contents of the file are in JSON format which defines various settings.

The file is created in [Documents/My Games/VirtualCast/config.json].

(The directory may be slightly different depending on the Windows environment, such as Document | My Document)

        "Comment2",
        "Comment3",
      ]
    }
  }

You can set a threshold of nico live NG score for the comments to spawn in the studio.
Comments with scores below the set NG score will be ignored.

  {
    "humanoid": {
       "use_fast_spring_bone" : false
    }
  }

When you join a studio with direct view mode, you can send your voice over from your mic.

config.json

  {
    "mode": "direct-view",
    "direct_view_talk": true
  }

This allows you to render the image on Looking Glass.
When you have your Looking Glass connected and join a studio with direct view mode on, you will be able to see the characters and items in 3D.

To use this feature, you need to launch the application in the “direct view mode.” Therefore, you must also specify “mode”:“direct-view”.

config.json

  {
    "mode": "direct-view",
    "enable_looking_glass": true
  }

It appears the loading of config.json has failed.

There are several possible causes:

1. The name of config.json file is not correct or the file is not placed in the same folder as VirtualCast.exe
2. There is an error in config.json

To load a model for the first time, you must agree with the terms of use associated with the model.
From niconico tab, login to niconico and enter the studio. (No need for streaming)
You will then see the terms of use for the model which you have to agree to use the model.

Other users can not use a model whose use is limited to the owner of the model.

Make sure the URLs are correct.
As shown below, the image will not be loaded when you specify a URL for a Twitter post.
https://twitter.com/priramen/status/1078961465481060352

You can load images by specifying URLs that ends with “.jpg” or “.png”.
Right-clicking on image and selecting “Open in new tab” will show you the URL for that image.
