AI Smoke Pods?

[Nybble]

Hi all, simple question.

 

I'm trying to build a mission for WWII dogfighting, where the aircraft start in the air, and have a limited combat zone. To enforce this I am using a trigger to explode any aircraft that leaves the zone.

 

However to prevent players from unknowingly straying out of the zone, I want to mark it by having AI aircraft fly around the edge of the zone with smoke pods enabled.

 

I've also tried getting aircraft to fly around leaving contrails, however I've had no success at any altitude.

 

Is there a way to achieve that, or is there a better way to create a dogfighting arena as I have described?

 

Open to any suggestions, or similar missions that allready exist.

 

Thanks!
