How to get a VPK
VPK from game files
First we need to find the VPK ID
You can find ids like this https://steamcommunity.com/sharedfiles/filedetails/?id=(this is the id)
When you join a server and accept a addon, they get placed in steamapps\workshop\content\730\(workshop id)
Simply open up the folder and there you have the (workshop id).VPK
If you don't have the VPK we can instead download it
Download VPK from Workshop
To download the VPK you will need SteamCMD and for simplifying the download Workshop Downloader
Download Manually
Open up SteamCMD Type the following commands:
login anonymous
workshop_download_item 730 (workshop id you want to download)
quit
And you will find the (workshop id).VPK in your steamcmd path/steamapps/workshop/content/730/(workshop id)
Download Automatically
Download the tool: Workshop Downloader
Place the .bat anywhere you want, then edit it with Notepad++ or any editor you want
Change cd "files/steamcmd"
to the path of your SteamCMD folder
Open up the .bat file and write/paste the workshop id you want to download
Then the (workshop id).VPK should be placed at the same location you opened the .bat file
