This upgrade guide describes how to upgrade to version 2022.2 of Unity’s built-in render pipeline. To upgrade to other render pipelines to version 2022.2, see:
To upgrade other packages, refer to the documentation for the packages you are using.
The Enlighten Baked Global Illumination lightmapping backend is no longer available by default. When you upgrade a project to this version, Unity removes the Enlighten baking backend from the lightmapper selection dropdown and substitutes a Progressive Lightmapper in every Scene where you’ve selected the Enlighten baking backend.
On Apple silicon devices, Unity substitutes the Progressive GPU Lightmapper for the Enlighten baking backend. On all other devices, Unity selects the CPU Progressive Lightmapper.
To continue using the Enlighten baking back end, open Edit > Project Settings > Editor and in the Graphics section of that menu, activate Enable Enlighten for Baked GI (Legacy). However, this option isn’t available in 2023.1 and later.
The Minimum Bounces property of the Progressive Lightmapper is no longer available in the Lighting window.
When you upgrade a project to 2022.2, Unity resets the Minimum Bounces value to 2, the recommended number of minimum bounces for lightmapping. To change this value, edit the LightingSettings API property minBounces.
In 2022.2, Unity updated the default versions of all tools used by Android. The new versions are as follows:
|Build-tools component version
|Platform (API level)
|31 and 32 added by default
|Android Gradle Plugin
The update to Gradle version 7.2 changed some build.gradle file configuration options. This required significant changes to Unity’s default gradle templates. Unity won’t attempt to upgrade custom Gradle templates to match the new format which means projects that contain custom template files might fail to build. To solve this, recreate any custom template files based on the new default template files.
For information about the
build.gradle configuration option changes, refer to the Android Gradle Plugin release notes.

If you have projects that were created with the Navigation feature in previous versions of the Unity engine you can do one of the following:
In either case, the AI Navigation package is automatically installed and added to your project.
To start using the new package you need to convert your project as follows:
As part of the conversion process, the NavMesh Updater makes the following changes:
If the NavMeshes in different scenes are baked with different agent settings then you need to create new Agent types to match those settings. To create the Agent types do the following:
When you have created the new entries you then need to do the following:
To find the settings that were used for each existing NavMesh, select the NavMesh .asset file in the Project window. The NavMesh settings will be displayed in the Inspector.
If your project uses the
NavMeshLink components defined by scripts downloaded from Unity’s NavMeshComponents GitHub repository , then remove those scripts and any associated files before you add the AI Navigation package to your project. If you don’t remove these scripts, you might get conflicts and errors related to these components in the Console. The new components mirror the same behavior as the old components do in your project except when using the following components:
NavMeshSurface component now includes an option to use only the objects that have a
NavMeshModifier in the baking process.
NavMeshModifier component to child objects in the hierarchy.
