I have created a new mod, and according to Wikidescription for creating a mod I should have 2 required files to make it properly detected by Server Browser in ArmA 3 Launcher to allow automatic download from Steam Workshop when a client clicks Join on the server, which is mod.cpp and meta.cpp with correctly set Steam Workshop mod id (taken from URL on mod page in Steam Workshop) and mod name. I have it all done, it's showing in launcher after I click Join as required on the server, but there is no option like on some other mods to download it automatically. More over, even if I take an existing mod and copy it / create it as a new mod of the same mod (repack) then it's not recognized also. More over there are multiple mods which are not recognized mods, but they should in Steam Workshop which is causing players to not join such server because they can't automatically get mods.
Example of mod which was repacked and is still not recognized:
Mod link: [[ https://steamcommunity.com/sharedfiles/filedetails/?id=2614017981 | MOD LINK ]]
Mods in startup param of the server are added like -mod="clientmods/2614017981;" (The directory name is also mod steam id of mod in Steam Workshop).
So they are pointing to folder with mod id (could this be an issue on Linux? According to my test it the same result with mod id or mod name).
Also, some mods indeed had steam mod id not correctly set in meta.cpp, so I have updated it manually on my server side, this also didn't help (only the name showing correctly after the change in Join server dialog / server details but still it's marked as red and not recognized for automatic download).
List of some other mods which are not recognized (some of them might have indeed incorrect id, but like I said below even after I update it to correct one after downloading it for server, it won't help, and some of them are correctly set both on my server and in Steam Workshop and still no luck).
- ACE RKSL Compatibility Nerexis Repack
- Kyklop's Electronic Warfare
- Map Darkmode ACE Repack Nerexis
- Plastic Armbands Repack Nerexis
- Realistic Drones
- Freestyles Crash Landing
- Tier One Weapons
- NIArms All In One (V14 Onwards)
I think the expected behaviour would be for ArmA3 Launcher to match it correctly for automatic download if the Steam mod id taken from Steam Workshop mod page URL is correctly set. It appears it's not matched by steam workshop mod id.
Also, If I manually export mods required by the server to 'preset file' and then, unsubscribe them in Launcher and then I import it back in the Launcher, then mods are correctly recognized for download from Steam Workshop.
One of problematic mods:
{F2567911}
Meta.cpp set correctly:
{F2567913}
List of some other mods not recognized:
{F2567915}
Can be directly tested by trying to join my dedicated server through Launcher, server IP:
88.99.137.120:2302 (Game Port)
88.99.137.120:2303 (Query Port)
