No Anti Aircraft (SAM) Rocket Smoke Trails
Closed, ResolvedPublic

Description

Within the latest developer version, I do not see any smoke trails during daytime from the 5-10 surface-to-air anti aircraft rockets being fired at my aircraft from the ground.

Steps To Reproduce
  1. Place some Anti Aircraft (SAM) vehicles, such as Tigris vehicles on the map.
  2. Set time for daytime.
  3. Fly over in a jet and notice no smoke trails.
Additional Information

If I'm not mistaken, the rockets burn a solid propellent and expel quite a bit of smoke or combustion.

I have yet to test night time, with and without using night vision. I would imagine there would be some sort of white flashing during the initial anti aircraft rocket launch until the flame is quickly shrouded by rocket exhaust and the angle of attack of the rocket blocking the light from the tail end of the rocket. Without night vision, I would imagine there would be some similar subdued effects.

(I'm also not sure if fixed wing air to air rockets are effected, or AAM, but do not think so.)

Finally using the 69th Enjin* server, I saw one AA missile trail from some infantry ground AA being fired at another pilot. (It was a very short, low, & quick flight for the AA missile toward the pilot head-on who was flying too low.)

So far ARMA 3 Version 1.40.129* still doesn't show any AAA missile trails from the pilot's perspective. (Can only see missile trails usually if you're on the ground or the one firing the missiles. If I'm not mistaken, can either sometimes or most times see infantry AA being fired at other pilots.)

After the latest patch, out of the 50+ SAM/AA/AAA (surface-to-air/anti-aircraft) missile fired (by two Tigris) during a fly-over at an altitude of >2,000 meters (for which the AI are now programmed and able to see unrestricted over 1,500 meters after the latest patch), I still think I only saw maybe one or two AA/AAA missile trails while viewing as pilot from external 3D view. If any missile trails, as the trails I saw from 3D pilot could have been only artifacts of the trails.

If you're on the ground as a foot soldier, I believe you can see missile trails without any problems.

If I'm not mistaken, this becomes a problem with passengers of helicopters, also not being able to see or detect ground AA/AAA fire. During the day, should probably be able to see small smoke plums (and possibly flashes at night) from the ground firing and then smoke particle trails through the air and possibly light some light flashing from the rear of the missile rocket motors.

This bug is currently unassigned.

Hi, I was unable to reproduce this issue (tested with Tigris and Wipeout). Are you able to reproduce this even in a simple mission created in the editor? Do you use any user-created mods? Thanks!

I use no modifications, just vanilla ARMA 3.

The equipment I additionally utilize and this bug then becomes extremely evident is Track IR hardware, and then viewing as third person during flying over AA vehicles. When flying in third person using Track IR, you'll notice there are almost no smoke trails from ground fired rockets! However, when viewing from another person's point of view from the ground and watching AA/AAA rockets go into the air, you can see smoke trails without issues. So this seems to only occur from the pilot's point of view, and easily seen in third person pilot seat, and might be more easily seen when using Track IR as it's difficult to move your head easily as third person via keyboard, etc, as the keyboard or joystick head movements are static, or limited to one limited angle and a limited span. Even when viewing externally and watching another aircraft fly over, you're still omitting from viewing from the pilot's seat.

I'm also wondering if at night (including hours of dawn and dusk), we should also be seeing flashes of light from the ground further indicating AA/AAA rockets firing, as well as light trails from the rocket motors? Others on the ground can easily see this activity.

Another but unlikely scenario, the smoke trails could be appearing as invisible from the angle of view with the colors used to indicate smoke trails and blending into the ground colors. It is very rare that I see any smoke trails and more like a fluke when I do see a rocket smoke trail, and I have yet to see any flashes of light from the ground AA/AAA firing at night. I doubt this has to do with the colors of the smoke trails, and I further mention below the only AA rocket fire smoke trails that I do see, might be coming from infantry AA rocket fire.

Maybe if I get more time, I'll put like 20 to 40 AA vehicles (Tigris) on the ground and fly over at a very high altitude, and at night. I'm wondering if decreasing the expertise will make them poor aimers, might aid further detecting this issue. But I think the magic here used for detecting this issue is using TrackIR hardware. Also, it maybe the rockets trails I do see are those only coming from infantry AA rockets and not the AA vehicles, or Tigris vehicles.

2015.04.28 01:00 UTC: I placed approximately 40 Tigris with low expertise on the map and used the Typhoon to fly-over using a view distance of about 3700km at an altitude between 3000-4000m. I now see some very brief white flashes of light, but no smoke plumes from the rocket motors. The flashes of light, or simulated rocket motor light, are so fast and so brief, I'm not sure it's even realistic as I wonder if the rockets can even travel at the speed of light. Usually when two objects are going in the same direction, the second object has more of a chance of being fully seen versus when two objects are moving at each other. Shrugs. Seems really odd to me. Maybe getting some experienced witness testimony as to what a pilot should be seeing from AA/AAA ground fire? ;-) (Also, there's still no tail number/art light when using collision lights at night. Aircraft use tail lights on their tail numbers to distinguish themselves from other aircraft at night. Main lights on aircraft still provide light while only on the ground, and main lights are never able to be seen once in the air.)

Thanks for the feedback. I am able to reproduce it now and it seems, that there is a smoke trail but is very transparent and practically invisible from an airplane. Thanks!

You're welcome.

This needs to be closed. This bug was fixed a while ago, and I now can vividly see when my own team is firing on my butt. @#$@#$ :-/

Thanks for the feedback. Marking as fixed.
