Yes they must. If you don't rename them then TrackIR will connect direct to the sim and chaos or a jittery display will result.

These are NPs (TrackIRs) own instructions and the only way to prevent it connecting direct. You will have to get admin rights to rename them.

Steve do the TR5 simconnect files still need to be renamed? I have checked the folders you instructed and I cant find them with Win search. I did find the Simconnect.manifestopus and Simconnectsp2.manifestopus1 files. Does Opusfsi change the files on its on now? Thanks.

Am setting up my new system.

I thought I'd post this here - apologies if it is the incorrect place.  I wanted to recommend a TRACKIR alternative that I have just purchased and installed.  It is called Trackhat: http://www.trackhat.org/

It is a system very similar to TRACKIR that can use the free Opentrack software.  It consists of a hat with three IR LEDs or a clip with 3 IR LEDs that you can attach to your headphones.  The main difference is that all-in it costs just £30.00 for a clip and modified webcam.  

It is easy to set up, and works with OPUS as it is able to emulate a TRACKIR device.  

I have it set up on my P3D system and it works a treat.  I have no affiliation with Trackhat other than being a satisfied customer.

You should NEVER run an AV program with FSX, P3D, TrackIR, or OpusFSX.

If you want to flight sim then shutdown your AV software completely.

You only need Windows Firewall. AVs are nothing but trouble and ruin performance and correct functioning of the software.

it appears when FSXTRACKIR runs, avast puts it into a deep screen check, only for a few seconds but enough that opus and tir software dont like it and close the link, have told avast to accept fsxtrackir and no problems since.

thanks for the support all working now

I have tried both TrackIR versions 5.1.3.Final and 5.2.2.Final with no problems. Although I did have to rename the three manifest files again in the NP TrackIR5 install folder.

Please double check you have done the above then check again for OpusFSX listed in the 'Tiles' title. Once connected (with FSX, TIR and FSXSERVER running) it is down to the NP TIR5 software to show OpusFSX as the Title within its window.

You could try reinstalling TIR version 5.2.2.Final version, don't forget to rename those manifest files again.

Try starting TrackIR after starting the FSXSERVER program just to see if that makes a difference.

I am back now so I will check to see what I get. But looks like yours is not connecting or attempting to connect to OpusFSX interface through its own NP SDK.

1,  I have no manifest files hiding, 

2, I am connected to FSXTRACKIR

3, My lights are on 

4, I have OPUSFSX in the games list

5, OpusFSX in the display - this is the bit i donjt think is working, as it says no title, however, i dont know how to get it to see OPUSFSX as the running program, I thought it would see OPUS when it started 

I have attached a screenshot

Double check that there are no manifest files hiding somewhere that will need renaming. Open the FSXTRACKIR program window and make sure TrankIR is connecting to it. It should be reported in the window. Nothing much else to do other than what's in the manual and the TrackIR topic here. Are your TIR lights coming on? Have you checked OpusFSX exists in the TrackIR games list, have you checked to make sure OpusFSX is shown in the TrackIR display.

TIR ver 5.2.2
P3d ver 2.2.1048.0
simconnect  2.2.0.0

I have installed the latest version of OPUS beta and also have TIR latest, i have renamed the simconnect files as instructed, 

I start TIR and then P3D then start OPUS, the fsxtrackir.exe is running and shows connected to FSX.

I have enabled TIR on the configuration window and set the priority to high, i have set scan to 12, XYZ to 0.50 and PBY to 0.50 

no matter what i do my trackir doesnt seem to track,

Stephen,

      Thank you for clarifying this. Sure would be awesome if that feature could be added. I have a 9 monitor setup with virtual cockpit views and it is very immersive seeing the cockpit interior as part of the simulation. If only I could move my head with TIR to look over the glare shield or look down out of a side window it would really complete the experience. Any thoughts about including this down the road or is the FSX / P3D code prohibitive? It would seem to me to be a natural extension of DHM effects on the clients which show motion of the airframe relative to the observer (ie: eyepoint).

Peter.

TrackIR is not meant to move the eye point on the clients. They are not couple views and do not work that way. The TrackIR interface coordinates the TrackIR head movement with the OpusFSX DHM and eye point movements on the main system only. It is not designed to relay all these movements across to the client systems which display their own camera views.

So bottom line TrackIR head movements are not relayed to the client systems.

Stephen,

   I use Virtual Cockpit views on all my clients for a panoramic setup. I have Track IR working through OPUS on my P3D server machine (renamed the manifest files etc.). Unfortunately, I cannot get my head movements to show up in the Virtual Cockpit Views on my clients even though TIR works fine on the server.

    I'm not sure if it has anything to do with it but I do have DHM enabled on the Camera Control page for the P3DServer Camera which is assigned to all aircraft types. I enabled Live Camera on the Server which of course greys out the General DHM Options on the OPUS FSI Server-Configuration page. Is this the correct approach?

     I've read the forum and the manual but can't seem to figure out what I'm doing wrong that prevents my TIR movements from passing through to my clients? Any advice would be appreciated.

     Thanks,

Peter.

You can also use the Live Camera Control LCC to move the eye point on a temporary basis. But to create permanent camera views you must use Live Camera and save your views. Please consult the Live Camera manual for further details.

You can use Live Camera to create your VC views. Normally you create them for each aircraft you fly. You can easily select a view then click on Add New Camera to clone the view, then just edit the view to suit your new aircraft. There are also CDF (Camera Definition Files) on our website, provided by users, these camera definitions can be Imported into Live Camera. Whichever method you use its a fairly simple process to create your views.

Hi,

Am I able to set up a VC Seat position for different aircraft.

EG If I set it up for the Cessna 152 and then change to the C172 it will move me to a diferent position or do I have to adjust every time I am in the cockpit.

If that is the case are there any keyboard commands I can use to do this?

Thanks for explaining, it makes sense now.

I like the idea of having to simulate adjusting your seat. Another step closer to the close as it gets for flight sim. Big smile

Live Camera Control (LCC) is not Live Camera (LC). LCC is used to make temporary adjustments to the eye point all coordinated with DHM and TrackIR etc.. There is no save option here as they are just temporary adjustments, like changing the seat height. With LC on the other hand you can create, edit and save camera views which are permanent. The camera views are saved by either pressing on the Save All Cameras or OK buttons in the Cameras dialog.

It is meant to simulate adjusting your seat, also allows you to walk or fly around outside on external custom camera views. It replaces the FSX controls to adjust the eye point which are not coordinated or compatible with DHM or TrackIR operation.

Hi Cheryl, I set my viewpoint with Live Camera and viewpoint was ok. After shutting down FSX and later when I got back in the sim, I had to reset my viewpoint. Live Camera didn't save changes permanently.
I don't see any save button on the Live Camera.
Should I be saving the flight with set viewpoint as default in FSX?
I'm not sure if I'm missing something.
 
You know, I guess by not saving, it kinda simulates adjusting your seat like a real pilot would do. Big smile

Can I adjust TrackIR view point without camera enabled. I have my view point setup in TIR through the camera, but with camera disabled my TIR view is off. If I enable camera view is good.

So, can I adjust the view within opus or do I need to adjust through TIR or do I need to adjust the eye point for TIR through the aircraft config. I'm not sure how to get my eye point adjusted with TIR without having to enable camera.
 
Thanks

I will soon be adding 'Run as High Priority' options for the Opus FSXTRACKIR.EXE and the NP TrackIR programs. Users have reported that setting, normally the NP TrackIR program, to run in High Priority has cured there otherwise jerky TIR response.

If you are still having problems after setting the TIR light levels (or creating special TIR sunglasses) then someone has recommended setting the process priority to High for the trackir program in windows task manager.

I put two polarized lenses from sun glasses on mine

I can keep the curtains open most of the day now as my lounge faces south and its only an issue in the evening when the sun is lower in the sky :)

My TrackIR camera does face the window as well and i have the pro clip and it all works sweet :)

Yes, the light levels can change in your room throughout the day and cause problems, even reflections from objects in the room or heat sources. There is an unusual tip here for fixing it,

Had the same issue when I recently bought OpusFSX. TrackIR was working perfectly on it's own but when switching to DHM there were random jumps. I looked up the Opus manual and slowed the scan speed right down to 40ms. That fixed it but all the smoothness in head rotation was lost.

In the end the suggestion in the OP of this thread fixed it. The problem was not the scan speed but was the light filter threshold surprisingly. With track clip I set the light filter threshold down to 70 and IR brightness to 12 with precision of 100 on standard with the Opus TrackIR scan speed set back to it's default 12ms.

That nailed the problem and is now working sweet. I am actually really surprised that the light filter threshold was the problem all along.

Try just turning off the turbulent bumps and leave the inflight turbulent motions on, and set all sliders to default mid way. I just couldn't fly without DHM, just not the same.

Hi Stephen, 

I use Opus every flight and love the camera system, but I have had to untick DHM due to strange goings on with TrackIR. 

Without DHM TIR is smooth and tracks perfectly without stutters. Tick the DHM box and every now and then the screen/cockpit will judder violently, just for half a second. 

It ended up getting annoying hence why I turned it off. I've tried different scan rates but that did not eliminate the problem. In the meantime I've reactivated Accufeel turbulence but if you have any ideas regarding DHM please shout, it may be just one particular setting.

Many thanks,
David.

They should just use the default settings and check there DHM and AHM movement, that will check their SimConnect, and users should have an idea how taxed their FSX systems are.

 
If you set the Opus scan rate too high you will eventually get a stuttery display, if you set it too low then the display will jump as updates are missed. All other jitters are usually down to TIR and the quality of the light signal.
 
We have tried filtering out data but that process must really be performed by the TIR driver and not after the fact in our interface which is really just relaying the data to the sim. Please do not read too much into the test data, the values may be rounded and are not intended as a user's analysis tool.

Thanks for this Stephen - I'll try some test runs in Debug mode and see whether it sheds any light (no pun intended). For the most part, I'm not affected by this flickering too much, but I am aware that it is a big pain for some users, and I'd love to find a reliable way to nail it.
I think part of the problem is that the same symptom (a single or few-frame 'flicker' back to a default eye-point and deflection; a reset view, in other words) is the same outcome for both of these causes (Simconnect overload and TIR light-pollution). This makes it very difficult for, shall we say, the normal everyday user, to work out what's actually the cause. They'll try messing with the Opus scan-rate in the hope of a fix, but if their problem is light-pollution, they may well simply add to their problems by introducing Simconnect overloading into their already difficult mix! They won't know, because the results both look the same! Conversely, if they go hunting for light-pollution and the problem is Simconnect timing out, they're wasting their time - and even if they think to alter the Opus scan rate 'for balance', they may not know whether to increase the displayed number, or decrease it. End result = frustration, and probably wrongful putting of the blame on Opus - a situation I am keen to avoid, because like you, I don't think it is the problem!
 
This is why I'm wondering whether, if Opus can detect spurious light-polluted garbage coming from the TIR end, and if this could be flagged up to the user (in debug mode or otherwise), at least this would help the average non-technical user know where to start looking. Conversely, if Opus hadn't reported any 'garbage-input' and the user was still seeing glitches, it would point to Simconnect overflow as the most likely cause, and he could begin looking there, and slowing down the scan-rate, maybe.

As I said, I appreciate this isn't your problem - but I don't like reading that other folks have dropped Opus in preference to inferior products, simply because they've not been able to make headway in solving it - and when they end up on these products (which probably put less stress on the Simconnect layer because they don't do anything like as much magic, and/or mean that the light-pollution situation has changed by the time they've reconfigured), they'll believe (wrongly) that they were right to have dropped Opus. All they see is that the problem has 'gone away', not understanding quite why. Human nature says that will simply reinforce their belief that Opus was at fault in the first place, even though that's inductive, not deductive logic!
 
All I'm thinking is that if Opus was able to detect 'nonsense' from TIR/NP and flag it up, it's in your interest to point the user to that end of this double-ended nightmare to start twiddling with! Get me?

To display our test outputs, just run the FSXTRACKIR.EXE program with a TEST argument. But the displayed test outputs depend on what I was checking the previous time, they are not meant to be for user information. The data may even be rounded for display purposes.

We already have test outputs displayed, that's why I know smoothing is a waste of time. You must weigh up both the speed of scanning the TIR interface via the NP SDK with the update frequency to the SimConnect interface. Go too fast for FSX and it can throw away updates, to slow and you get slightly uneven panning.

NP themselves say most flickering comes from extraneous light hence they recommend everyone should adjust the TIR light sensitivity to suit their environment.

If your DHM and AHM can move smoothly without TIR then the SimConnect interface should be OK with a correct setting of the Opus TIR scan rate. I use 12ms or 18ms. Increasing the ms rate decreases the frequency at which the TIR interface is scanned.

The Opus TIR interface simply takes the raw data from the TIR device via the NP SDK interface, scales it, combines it with the current Opus eye point data, applies any limits and submits it to FSX via SimConnect. It is a very simple process and so far all jitteriness has really been as a result of needing to adjust the Opus scan rate and change the TIR settings, with the vast majority of jitters caused by extraneous light.

I take it from that, that I was correct in my thinking that INCREASING the number in the scan rate box actually SLOWS DOWN the rate at which data is fetched from the NP interface, yes? (Apologies to labour the point, but I need to get this straight in my head, and I'm sure others do too).
 
As regards logging - all totally understood and concurred with. I had expected as much. I wonder if perhaps an alternative strategy for debugging might be better? How about a facility in Opus which examines the 'feed' of data coming from the NP interface and flags up (in a log, most likely) any instances where the deflection exceeds a physically possible amount in a single frame or small number of frames. At least then we might be able to determine if the cause of the 'glitch' flicker really does stem from TIR's end (which is my hunch), and positively rule out Opus's 're-server' as the cause. In essence, fit Opus with a 'garbage-in' detector, and have it flag it when that occurs!
 
As I said, it's my belief that the flicker stems from extraneous light in TIR - but this is extremely difficult to pinpoint empirically, because by the time one has left the sim and pulled up the TIR panel, switched to camera view and hunted for red-traces, the sunbeam which caused the problem has gone behind a cloud and is no longer reflecting off the door behind/beside you, etc, etc. There is no 'sanity input' logging in TIR's program, so Opus is effectively the only 'tap' on that data.
 
Of course, if the problem is ALSO caused by an overload of the Simconnect interface (entirely possible, given what I know about Simconnect), then it'll be much harder to trace - because presumably Simconnect doesn't have the capability to politely inform Opus's outgoing 'pump' that Simconnect is unable to process it, and instead, Simconnect will presumably quietly drop data without warning. If that's the case, only some kind of Simconnect logging within FSX itself will shed any light, but I've not looked into that yet (but it might be worth it, if I have time).
 
At least if Opus was able to flag up 'dodgy data' coming from NP/TIR in the first instance, that *might* eliminate (or pinpoint) one of our lines of enquiry, perhaps? I am confident it's not Opus that's the problem (I'm sure I've seen these random one-frame flickers even before Opus, tbh, but perhaps less often - but then I didn't have anything pumping weather info in via Simconnect, so it could still be Simconnect's fault, rather than Opus's). But Opus could, in theory, prove its own innocence, and conclusively point the finger at NP/TIR, if the faulty data came from there.

With the scan rate, which is approximately in milliseconds, you must consider the response of your FSX system's SimConnect interface and the NP SDK interface. Going faster does not necessarily mean going smoother. You may end up going too fast for the interfaces and so miss many of the updates, possibly resulting in a more jerky display.

The best thing to do is balance everything so that it can run optimally and hence smoothly. All systems are different hence we allowed users to adjust the scan rate.

Stephen

P.S.

Data logging would generate huge amounts of data, literally gigabytes. Also data smoothing is best done at source since it has to take into account other factors and settings. The actual data can be reported via the NP SDK at a very fast rate so the smoothing has to be undertaken by the actual TIR software. That's really were it belongs, all the interface does is relay this data on to the FSX display after superimposing it with the Opus eye point data.

Can I beg clarification on a couple of items gleaned from re-reading this thread a couple of times today, please?

Firstly - PBY scaling; I've found an answer to what it means here, but I don't believe I found it spelled out in any of the various manuals/guides included with the product. It might be worth ensuring that PBY - Pitch, Bank & Yaw - is made more obvious in the docs, perhaps? And with a note to the effect that if you can't turn your head fully round, it'll most likely by the PBY scaling factor that's the cause (which might stop folks returning to EZCA, etc).

Second - some of Stephen's posts mention reducing IR LED emission levels down to 15 or less - this is ONLY pertinent if you are using the reflective TrackClip (wire frame widget on the baseball cap), and conversely if you are using the TrackClipPro, it's an absolute no-no (you want IR levels to be OFF, as per my tip above), or you may suffer random IR reflections that confuse the camera.

Finally, I'm trying to determine what the scan-rate setting in Opus actually equates to. It's measured in milliseconds, from what I can tell, but if so, logically this means that a 30ms scan-rate is SLOWER than a 2ms scan rate, surely? By that I mean, if the INTERVAL between scans is 30ms, this is fifteen times less frequent in grabbing TIR data than a 2ms setting, presumably? Reason I bring this up is because various peeps (myself included) have talked about 'upping' the scan-rate, or 'increasing' it - when in fact, if we enlarge the number in that box, surely we're actually slowing it down, or increasing the interval, rather than the speed. It might be useful to have some confirmation on that point because it may prevent confusion in the future (if someone suggests 'speed it up' but actually means - without realising it - quite the opposite, well, you can see how that might end up complicating matters, rather than helping them!)

One last, last item - is it worth enabling some kind of 'input-output TIR data log', in Opus, so that we can keep track of what Opus is doing with TIR's data, and whether TIR itself, or Opus's handling of it, is the problem? I appreciate this might generate some pretty huge files (if scanning at 1ms, for example!) but perhaps might be worthwhile. From what I can tell, *usually* the cause of these 'one-frame resets' or occasional flickering, is the light threshold in TIR being momentarily confused, but I couldn't put my hand on my heart and say it's *always*, *exclusively* that reason alone. There are times when I'm scratching my head, and gritting my teeth, and maybe can't find anything obvious on TIR's panel to account for it - then next day, it'll be fine, without me having changed a thing, knowingly, at least.

Another, final, final, final ;) suggestion: perhaps is it worth introducing some 'TIR smoothing' in Opus itself? Simplistically, don't allow a reversion to zero XYZ/PBY coordinate on a single (or short number of frames), if the previous frame was greater than a certain deflection? I appreciate I'm saying this whilst blind of all the inner workings of what Opus is actually doing, but you probably get what I'm meaning. Not really 'smoothing' - more of a high-deflection-to-zero-deflection over a short time-frame 'filter'. Obviously, if the problem is SimConnect dropping the ball when it's busy, this won't help, but I mention it just in case it's worthy of investigation.

Thanks either way. :)
