The Unreal Engine directory contains UE_ROOT/Engine/Build/Build.version
.
This file contains a bunch of version information about the current version.
It should contain a value for Changelist
, but git working copies doesn't.
It is still possible to build and use Unreal Engine, but it is incompatible with the official Windows Unreal Engine binaries downloaded by the Epic Games Launcher.
The problem is that assets saved with the git version won't write a valid engine version to the asset files.
This causes the Windows Unreal Editor to write a warning for each asset.
Asset saved with empty engine version
By setting Changelist
in UE_ROOT/Engine/Build/Build.version
to the same value as the official Unreal Engine binaries we fix this warning.
