Source Control

If you intend to use a custom engine build, you will need access to UE5 via source control.

If you will only use official engine releases installed via the Epic Games Launcher, you can skip this step. In that case you will get packaged engine builds from Epic, and you won’t need to access their source control repositories.

Community Access

For UE5 Community member developers, Epic makes Engine Releases available on GitHub.

If you don’t have a custom license, but you still want to build a custom engine, then Github is how you will access the engine source.

UDN Perforce

Epic uses Perforce internally. They publish the Engine, Game Samples and more to custom licensees on UDN via a Perforce server.

This section ONLY pertains to custom licenses. You’ll know you are a custom licensee because you will have had to sign an mNDA with Epic and pay a licensing fee.
