Building an Unreal Engine project

UET can build Unreal Engine projects using just the .uproject file. For a more complete list of options, use uet build --help.

Building a project​

... using the engine specified in the .uproject file​

To build a project using the version of the engine configured in the .uproject file, run:

uet build

... using an installed engine version​

You can build a project using a specific version of Unreal Engine installed through the Epic Games Launcher with:

uet build -e 5.3

... using an engine from a specific path​

You can build a project using an Unreal Engine located a path on your computer with:

uet build -e C:\Work\UE5

This can be a path to either a source engine (e.g. cloned from GitHub or Perforce), or an installed engine build that has been copied to that directory.

... using an engine from a UEFS package tag​

You can build a project using Unreal Engine stored in a UEFS package with:

uet build -e uefs:container.registry.com/package/unreal-engine:tag

Advanced options for building projects​

uet build provides additional options to configure the way that the project is built. These options can be used in addition to the engine specification above.

... for a project that is not located in the current directory​

If the project is not located in the current working directory, you can specify the path to the folder that contains the .uproject file with:

uet build -p C:\Path\That\Contains\Project

... for the Shipping configuration​

By default uet build will build the project in Development configuration. You can build for Shipping instead with:

uet build --shipping

... for additional platforms​

By default uet build will build the project for the host platform. You can build for additional platforms by specifying --platform one or more times, for example:

uet build --platform Android --platform Linux

... with strict includes enabled​

To ensure all #include declarations are correct in your project, you can turn on strict includes. This will significantly increase the build time:

uet build --strict-includes

... and storing the resulting build elsewhere​

By default the project package for all platforms will be stored underneath Saved/StagedBuilds. You can specify a different output directory with:

uet build --project-staging-directory C:\Path\To\Output\To
