Cesium for Unreal has a continous integration (CI) system that automatically builds an installable version of the plugin for every commit in every branch. You can download and install these yourself to try out new features before they're released.
Before you begin, back up your project. Cesium for Unreal can not guarantee that levels saved with a pre-release version will be loadable in other versions of the plugin.
- Download a pre-release version from a Pull Request
- Download a pre-release version from a Branch or Commit
To download a pre-release version built from a pull request, click the "Checks" tab at the top of the pull request:
Then click the "Cesium for Unreal on: push" link:
And scroll down to the Artifacts section:
If there is no Artifacts section on that page, it's probably because the CI run is still in progress. Artifacts don't appear until the build is complete.
Find the appropriate ZIP file for your version of Unreal Engine. For example, CesiumForUnreal-52-*.zip
is for Unreal Engine 5.2. Note that artifacts that name a platform will only work on that platform, while artifacts without any platform in the name will work on all platforms that Cesium for Unreal supports. So in most cases you should download an artifact without any platform in its name.
Once you've downloaded the appropriate ZIP, move on to installing a Cesium for Unreal ZIP.
To download a pre-release version built from a branch (or a commit), click the green check ✔️ at the top of the list of files in the branch:

Once you've download a pre-release ZIP file using one of the methods above, you can install it into your Unreal Engine as follows:
- If you previously installed the Cesium for Unreal plugin via the Unreal Engine Marketplace, uninstall it first.
- Find Unreal Engine's
Engine/Plugins/Marketplace
directory. For example, on Unreal Engine 5.2 on Windows, this is typicallyC:\Program Files\Epic Games\UE_5.2\Engine\Plugins\Marketplace
. You may need to create theMarketplace
directory yourself. - If the
CesiumForUnreal
subdirectory already exists in thisMarketplace
directory, delete it first to make sure you're getting a clean installation. - Extract the release ZIP into this
Marketplace
directory. If you've done this correctly, you'll find aCesiumForUnreal
sub-directory inside theMarketplace
directory.
