Config injection during packaging

Overview of how to inject information into config/ini files during packaging

Config injection during packaging

Sometimes you want to change variables in a config/ini file during packaging. This can be done by adding the following line to your build command:

-ini:<ConfigFile>:[<ConfigSection>]:SectionKey=SectionValue -SaveConfigOverrides

When injecting arrays use the following syntax:

-ini:<ConfigFile>:[<ConfigSection>]:SectionKey="{ElementKey='ElementValue';...}" -SaveConfigOverrides

Example config file

In the following examples we will use the DefaultEngine.ini file as an example. This can be changed to the another file by switching out the <ConfigFile>. You will need to not use the Default moniker.


Example with single variable

RunUAT.bat BuildCookRun ... -ini:Engine:[ExampleSection]:AVariable=NewValue -SaveConfigOverrides

Example with array

RunUAT.bat BuildCookRun ... -ini:Engine:[ExampleSection]:AnArray="{FirstElement='NewValue1';SecondElement='NewValue2'}" -SaveConfigOverrides
