Rendering Pipeline

Currently, the default Inworld avatar (based on Ready Player Me) is only worked in Build-in pipeline. But all the later Ready Player Me characters you created by support both Build-in and URP naturally. We'll add HDRP support in the future. Moreover, you can always work around by creating your own URP/HDRP avatars and attach InworldCharacter scripts.


Unity cannot proceed Android build by 2021.3.6f1. It’s a known bug for Unity. To solve this, you need to copy the whole Tools folder from the previous Unity version. Check this page for more details.


1. Allow Access for grpc bundle

MacOS will automatically delete the grpc_csharp_ext.bundle which is necessary to our package if privacy is not allowed. Once you click the Play button, the following message box will appear,


Navigate to System Preferences > Security & Privacy and click the Lock button. When the grpc_csharp_ext.bundle appears under the Security & Privacy panel, click Allow anyway.


Return back to Unity, and click Cancel in the message box. Do NOT click Move to Trash. The dialog may appear again. If it does, then click Open once you have allowed success.

2. Compatibility with the MacOS build

This is a known bug for Unity, which will be fixed in version 2022.2.X.

3. Lipsync with M1

The current lip sync dll doesn't support M1. We'll upgrade our backend to support in future.

To work around this feature, you can just delete the LipAnimation below in your scenes.

If you are building an iOS application, then you need to add the Microphone Usage Description to your process build.
