You will need to set an environment variable that will tell to the build script where is your UE4 installation.

• Open a terminal
• Write setenv UE4_Path **[Path to the root of your UE4 installation]**. Add " around your path if there is spaces in it.

  • setenv UE4_Path D:/Softwares/UE_4.18
  • setenv UE4_Path "~/softs/my UE4 installation"

• Enter the directory BuildPluginTools
• Start Build_RPRPlugin_XXX.bat with XXX being the version you want (using double-click)
• Wait for everything to be setup. It will take a while since it will compile the whole plugin and copy some binary/image files.
  
• Once your build is over, go to PluginStaging\UE4_[YourUE4Version]
• Your plugin is right here, ready to be zipped in hosted

You can also use Build_RPRPlugin_All.bat to build on all versions.

• Open a terminal
• Navigate through RadeonProRenderUE/BuildPluginTools (use cd and ls to respectively move among the directories and list files in the current directory).
• Start the build script using ./Build_RPRPlugin.sh
• The UE4_Path should be displayed at the beginning. Check that it is correct.
• Wait for the build to be completed. Press Ctrl+C if you want to abort the operation.
