Unity SDK 4.0 lets you create and customize your own avatar creator within Unity
For some time, we have been developing the engine-native Avatar Creator for Unity as a separate project due to its initial readiness level, which required its own versioning and release cycle. Now that it has been launched, we are integrating it into the core SDK. This consolidation will simplify its utilization for developers.
We also decided to remove the auto-replacement of the avatars in the scene, when the avatar with the same ID was already in the scene to give you more freedom in avatar management.
Please note, that this is a breaking change.
