Source-built Unreal on Windows: a shared engine association

Modifying Registry Entries for a Source-Built Unreal Engine

BAT Commands

Create a BAT file and enter the following commands

set str=%~dp0
set name=%~n0
REG ADD "HKCU\SOFTWARE\Epic Games\Unreal Engine\Builds" /v "%name%" /t REG_SZ  /f /d "%str:~0,-1%"

This script adds the Unreal Engine source in the current path to the registry, using the script’s filename as the name The benefit is a consistent version identifier in the source engine’s .uproject files This prevents different registry names for the source engine on each computer from causing differences in the .uproject file and triggering recompilation
