Install Steam Workshop with SSM

To Install Workshop items with SSM. using the install-ws command. Check the server Variables-*.ps1 for these lines.

#                            Workshop Mod dir 
$global:moddir              = "C:\Users\ssm\Steam-Server-Manager\arma3server\Mods"
#                            Regular Game App ID 
$global:reg_appID           = "107410"
#                            WorkShop Mod IDs 
$global:wsmods              = @('450814997','463939057','773125288','773131200','843593391','1439779114','333310405','1374639840') 

if not add them. $global:moddir is for the install location in the server files. $global:reg_appID is the App ID of the regular game, not server App ID. $global:wsmods is the workshop IDs of the items you want to install. You still may need to enable mods in the launch params or the server.cfg. This will use Steamcmd to download the workshop items and copy them to the mods folder.

there is a Steamcmd workshop download size limit. I want to say it's somewhere @ 4GB. some Arma mods are like 5Gb and will fail.
works for a lot of good stuff like Astroneers, Ark, and games that do not have a workshop installer. Gives you a way to auto-update workshop items.

caveat: does require a steam login. SSM will do a test login and ask if it was successful.

if you don't want to use your primary account. I found it works with game share accounts.
