Here’s a small tool I’ve written to replace Gearbox’s WorkshopTool, which allows uploading the content of any folder as a workshop item.
This means you can upload things like prebuilt .big files and .webm videos.
You can download it at Releases · LonewolfWorkshopUploader (github.com)
To use it, make sure you have launched and login to steam on your PC, and simply edit the buildconfig_example.json file as you want, then launch a Command Prompt and run:
cd C:\path_to_the_directory_containing_LonewolfWorkshopUploader\
LonewolfWorkshopUploader.exe buildconfig_example.json3 posts - 2 participants
