- Just use Fallout 76 Quick Configuration
Or manually:
- Extract it in the Fallout 76 Data folder
- Open Fallout76Custom.ini(Or Project76Custom.ini) located in Documents/My Games/Fallout76 and add the names of the extracted ba2 archive to the sResourceIndexFileList string separated by a comma. It should look something like this:
[Archive]
sResourceIndexFileList=Something.ba2,DriverNephi(---).ba2
