Thanks. Can you try deleting C:\Users\chris\Saved Games\DCS.openbeta\Scripts\Export.lua and then rerunning the Tacview installer? You will also have to reinstall your other add-ons. 

https://tacview.net/download/latest/

If you don't want to have to reinstall your other add-ons, you could also try opening C:\Users\chris\Saved Games\DCS.openbeta\Scripts\Export.lua and editing it to put the Tacview line first

local Tacviewlfs=require('lfs');dofile(Tacviewlfs.writedir()..'Scripts/TacviewGameExport.lua')

Let me know how it goes!

Ok just done a complete windows 10 install and re-installed everything but it still only records my aircraft?

I have attached the log

Hi,

According to this log you are flying on a server which does not allow object export

2024-01-28 12:49:32.280 INFO    TACVIEW.DLL (Main): Export rights granted by the host: PlayerPlane=[1] PlayerSensors=[0] OtherObjects=[0]

Hope this helps!

Hello, is there a way to translate a tacview file from DCS into a "database" of activities?  For example, missiles shot, by whom, towards whom, weapon, hit/kill?, etc?  Can just be a list of events from DCS (S_EVENT_SHOT, S_EVENT_HIT, etc).  Something like this table (from the DCSServerBot).

nullThe events can be displayed in Tacview...but is there a way to extract shots and kills?

Hi, I have been trying to use Tacview...but it's only record the first few minutes of a flight. 

 

How long do you need to wait before exiting a mission to have the program finish saving all the flight data?  Is there some indication when it's 'caught up?'

Depends on the server. Some allow you to disconnect instantly, while some will delay the export to TacView, so you will have to wait some time for it to record everything before you can disconnect. Default seems to be 10 minutes, but check the ingame chat, it should tell you there how long you will have to wait.

Hi all!
Anyone using the PHPTacview addon? Is it possible to add flight time?
I looked in the PHP file, but coding is not my strong suite

We are in the trial period with two copies of Tacview. I connected to my friends session and we viewed the mission together. Loaded another mission and got missing data alert. I could only see grey surface with small x x x with some big X X X but no actual mission data. Tried loading the one we had just successfully viewed and it did the same thing. All missions loaded from the point on had the same result when connected to view together. We swapped so that I was hosting and same issue was present.  We were about to buy the standard and glad we ran into this before we did. Would like to get this resolved before moving forward.

Can we expect strategic view to be included in the standard edition of TV2?

[Hyperlynx]

Tacview isn't recording any more, for me. I just bought the Advanced version, too

I went and used Process Monitor to see where it's trying to save the files. It is using the usual location, except it looks like the calls to create the file is failing!

What's going on?

It turns out Tacview couldn't access Documents\Tacview any more. I changed where it saves to using the details at https://www.reddit.com/r/hoggit/comments/rzip4n/change_tacview_save_location_on_server/, and everything worked fine.

 

[RubberDogSh1tOutOfHKG]

Kola Map support?

[jetsimace]

Is anyone else having issues with downloading Tacview version 1.9.3 ?
(I have tried Edge, Chrome and Firefox at https://www.tacview.net/download/latest/en/)

Update 2024-06-27: Download via Onedrive is working fine.

I cannot seem to be able to find documentation about what the "γ" (small gamma) variable in Tacview telemetry is, except that the 1.9.1. change log states that "Path α has been renamed to γ to match NASA documentation".

It seems to mostly match the aircraft's flight path as indicated by the flight path marker (FPM) in the HUD view, but not always, especially during high-G maneuvers during which γ lags behind the FPM (see post below):

So, what exactly is γ and, more importantly, could it be made exportable?

Hi, see "Flight path angle γ" here: https://en.wikipedia.org/wiki/Aircraft_flight_dynamics

I don't know why it isn't on the export list. We'll add it. Thanks for the idea.

[Stickler]

EDIT: Found the reason for the below. As per Formulas | Tacview Wiki | Fandom, Tacview exports GS/VS/TAS as the rolling average over the last second. The exported values therefore lag the actual value.

---

I have noticed what seems to be a discrepancy in speed export.

Reference the following data recordings from a drop of a Mk-82 Snakeye in High Drag mode on a standard day, no wind.

The following orange table shows data from the telemetry .csv.

Note (marked in yellow) that the KTAS exported by Tacview at specific timestamps (Unix time) does not match the TS as indicated in the F2 view at the same time stamps (screenshots and the blue table).

As soon as GS and VS are available, I used Pythagoras to calculate KTAS (second column in blue table) to verify that KTAS data export is congruent with other exported data.

Note also that ASL export matches the F2 data exactly, so the issue seems to be specific to (true air) speed.

The discrepancy seems to be largest around the time when the Snakeye retarder blades deploy (0.2 seconds after release) and the bomb experiences an extreme rate of drag increase.

Can anything be done to increase accuracy of the export?

EDIT: Could there be an option to set the length of the rolling average period?

Hi, thanks for your enthusiasm! There's the FAQ here: https://tacview.net/documentation/tacview2faq/

And on the Discord there's a channel where you can ask more questions: https://discord.com/invite/qe26hQzSSf

There's no release date yet.

A couple of quick questions....

1) Is it possible to remove the object ID info for missiles from the selected aircraft?

2) Is it possible to hide the separation data box in the middle of the dogfight line?

 

Many thanks

1) Do you mean like the label? You can customize the labels or turn them off altogether via the Display Object IDs menu - see screenshot attached. The label of the missile will mirror the label of the aircraft.null

2) Between the two object selection drop down menus there is another drop down menu where you can un-tick Display in 3D View - see screenshot attached.

Breaking the Radio Silence!

I have one foot in each camp: as both a simmer and a developer, I understand the frustration of not hearing about your favorite product for years, wondering if the project is still alive or making progress. On the other hand, I know the fear of communicating about an unfinished product, afraid of being misunderstood or misinterpreted.

Today, I've decided to break the radio silence and not just talk to you—but show you where Tacview 2 stands. This titanic project, started years ago, is very much alive and moving forward, albeit slowly but surely. I'm just as eager as you to see it completed. At the same time, I don't want to rush it like I did with Tacview 1 back then, so I've decided to take the time necessary to ensure everything is done properly.

I invite you to visit the dedicated page I’ve just created to learn more about the current state of the project.

Will there be a box version available?

@Vyrtuoz

It looks like the AGM-84 SLAM-ER is not being properly recorded in multiplayer. On the server tacview it seems to just carry on forward, while on the client of whoever fired the missile, the path is properly recorded and you see the missile connecting with its target.
