Go to your engine’s build batch files folder
For example, the directory for my UE5.3 is C:\Program Files\Epic Games\UE_5.3\Engine\Build\BatchFiles
Right click on empty space to open terminal
use" .\RunUAT.bat " function to rebuild your plugin.
For example:
.\RunUAT.bat BuildPlugin -plugin="D:\copy your directory of the current plugin here\InworldRPM\InworldRPM.uplugin" -package="D:\Plugins\create a new folder to store the rebuilded plugin\InworldRPM.uplugin"
Then we can just copy and paste the content of the rebuild plugin to replace the existing one.
