The system works specifically on dedicated servers. If you are hosting through yourself it may not work properly for you specifically. I believe everyone else will see it working properly.

does the host specifically need to activate it?

sorry, whats annoying is that in SP it works if i just place down the composition but in a private multiplayer server when i place it down it changes nothing to the actual game.

No idea what you mean by that. This system is only loaded if you choose to have it loaded. If you find it annoying, specify what is annoying or don't run the system.

This is a great mod but its so annoying when i try to play a private server with my friends, is there any solution to this?

I can look into it, I honestly thought that trim was already a thing. Turns out its just for helicopters.

Is there a way to add trim for aircraft, by any chance?

Some mods are compositions (like this one) and won't appear in your mod list from the launcher. Instead they will be available in eden or Zeus. From the editor, click the groups tab and go to the empty section. There you'll see workshop content at the bottom.

Is their like a reason i cant download any arma 3 mods from the workshop anymore like what happened i cant figure out what the problem is half of the workshop mods have 0 stars for me ones that used to have 5 and when i click subscribe the mod says downloaded but it does not show ip on my arma mods list this ones 4 stars for me and im into planes i thought the lights in the video were cool but i cant download it anyone know whats up

Does this only work on default aircraft?

Is this client side, server side or client+server?

Potentially, we'd have to experiment with it.

great mod! can you make helicopters be able to withstand damage from heavy AA vehicles?

Incredibly based.

Aircraft collision light changes have been disabled due to how lightpoints work in Arma 3. Since they don't function as seamlessly as actual reflectors created in configs and lag ahead of the aircraft when moving.
