Install Muse Common with the Package Manager
From Unity Behavior version 1.0
onward, the Muse Common package is no longer included automatically as a dependency. Consequently, Unity Behavior disables the generative artificial intelligence (AI) features by default and doesn't compile them. To enable these advanced features and maintain control over the additional dependencies in your project, install Muse Common manually.
To install Muse Common, follow these steps:
Launch the Unity Editor and open the project where you want to install Muse Common.
In the Unity Editor, select Window > Package Manager.
The Package Manager window opens.
From the Add menu, select Add package by name….
In the Name field, enter
com.unity.muse.common
.(Optional) In the Version (optional) field, enter
2.0.5
or a later version.The minimal supported version of Muse Common is
2.0.5
.
