Legacy SDK


Support for VRChat's legacy SDK ('.unitypackage' SDK) is ending in 2022.

  • To create new projects, use the Creator Companion or a template.
  • To update an old project, follow our [migration guide] by using the Creator Companion.

The legacy SDK refers to the 'old' SDK package format distributed in files such as VRCSDK3-WORLD-2022. If your project's Assets folder contains a folder named 'VRCSDK', then your project uses VRChat's legacy SDK.

New updates of the SDK will be available for the legacy SDK until 2022. Starting in 2023, new versions of the SDK will only be available through VRChat's Creator Companion or one of our world or avatar templates.

To ensure that you'll be able to easily update your VRChat projects, please use one of the above methods to create new VRChat worlds. To upgrade your existing content, please use our migration guide.
