The solution I’m using is the following:

- Compile the plugin using the command line:

> “ENGINE\_DIR\UE\_4.22\Engine\Build\BatchFiles\RunUAT.bat” BuildPlugin -Plugin=“PATH\_TO\_MY\_PLUGIN\MyPlugin.uplugin” -Package=“PATH\_TO\_BUILD\_FOLDER” -TargetPlatforms=Win64 -Rocket -precompile

- Obviously replace **ENGINE\_DIR** , **PATH\_TO\_MY\_PLUGIN** , **MyPlugin** , **PATH\_TO\_BUILD\_FOLDER**

- **Note** that you should either add **-precompile** to the argument (as above) or put **bPrecompile=true** into your build.cs files

- After building the plugin is done **add/replace bPrecompile=true with bUsePrecompiled = true**

- Delete all the .cpp files (in the source and intermediate folders) (Untested: you can even delete the header files but then you can’t extend the cpp classes anymore)

- Your plugin is now ready to use without the source code
