I see. Yeah, that would be very tedious indeed.

Thanks for looking into the issue, much appreciated!

Maybe you could add some code that categorizes units / gear option / liveries into three subtypes: "winter type," "non-winter type," and "no winter type available." The code would check each item for "winter" in its name, placing it in the appropriate array. If no winter options are found, the item goes into the "no winter type available" array. Finally you set up the pool from which players and AI can select stuff depending on if the selected faction contains "winter" and on if the player has enabled an additional "include units/gear without winter option" parameter.

Something along those lines might work for factions whose devs have neatly labeled everything, as seems to be the case with those from the Global Mobilization DLC?

@moon.shadow789 I missed the 'or vehicles' in your post. There is an option to choose the vehicles that will be used, but you need to select all the vehicles you want, so that could be tedious. Look at the parameter for 'choosing vehicles using the garage interface'.

I'll see if I can figure a way for it to know which vehicles to spawn.

Thanks for the quick reply! At least for me and a friend using the sub faction selector does not completely work as intended with Global Mobilization content: It allows us to get rid of the winter camo infantry, but not vehicles. A significant percentage of all vehicles (both friendly and enemy, spawned as static in the base or dynamically in use) is still in winter camo. 'Select units' only covers infantry as far as we could see. Are we overlooking something?

Yes there is. There is a checkbox on the faction selection screen to show 'sub factions'. Some factions aren't broken out really well, so using sub-factions can help. For even more granularity, you can use the 'select units' button to choose individual units to use.

Great work, thanks for creating this mission!

One question though: Is there a setting to prohibit winter camo units from spawning? Encountering bright white infantry units or vehicles in summer ruins the immersion and experience a bit, tbh. Thanks in advance!
