AAA barrage fire workaround

[sirrah]

Does anyone know a work around to get something that looks like AAA barrage fire? (without the need of scripting)

 

I've been trying to get AAA fire at drones, but so far that looks really silly.

 

The idea was, to have 2 immortal predators spawn when the player gets near, by a simple trigger action. This obviously works and the AAA does fire at the drones, but..

 

I need to have the predators fly pretty low in order to get AAA firing at them, so I can't "hide" them in a thick cloud deck. Mission I'm working on requires low flying, so the predators are highly visible once you get close to them, which makes everything look really weird. Setting the drones to "invisible" also makes them invisible to AAA

Nearby SAMs also fire at the drones (placing some static object to block their sight, solves that issue though)

 

Is there maybe a way to make the drones invisible for the player, but not to AI units?
