It's recommended to watch the above setup guide, but here is the outline:
Ensure the Geometry Script plugin is enabled in the Plugins window and then close Unreal
Copy the downloaded Volumator folder to your project's 'Plugins' folder (if you have no Plugins folder, create one first)
It's possible that FAB did the above step for you depending on how it handles plugins
Rebuild your uproject:
Generate visual studio project files on the .uproject
in VSS (or your IDE) select Development Editor and your platform
Build your project
Restart Unreal, Volumator should now appear in your Plugin list
In your content browser navigate to: Plugins/VolumatorContent/Volumator/
Right click EUW_Volumator and select 'Run Editor Utility Widget'
Run through the setup wizard, this will guide you through setting up a bunch of basic defaults
The wizard includes a section on how to add an editor button to your Unreal toolbar, so you don't have to navigate to Volumator in the content browser again
If you choose to not add an editor button, you can instead easily open Volumator again from the content browser, or if you've opened it in the past it'll show up in Tools > Editor Utility Widgets
Opening Volumator in the future will use the defaults you specified during the setup wizard. You can run the wizard again from the Help menu to set the basics, or open DA_Volumator_Defaults and tweak them allÂ
