Make your own command

You can extend uetoosl for your organization by creating plugins. A template is provided to help you get started.

  • Windows & Linux

  • Open projects

  • Build

  • Run automated tests

  • Cook

  • Generate localization files for internationalization

Unreal engine has 222 comandlets, 83 commands and more than 1237 command line parameters hidden inside its code, very few are documented.

uetools identifies the useful arguments and bundle them inside a command line utility, forming groups/set of arguments with a singular purpose.
