I'm using OpenTrack for Arma to track my headmovements. It works in Arma but my charcters camera jumps to a fixed point on every axis at roughly -20°. In other games it works perfectly. I've testet FreeTrack and Track IR but both protocols have this issue.

FREETRACK - how to make it work very easily (wiimote))
darkcochon posted a topic in ARMA 3 - TROUBLESHOOTING
Hey there, I've found a very easy way to make Freetrack works with A3. First off: be sure everything works great and smooth; Try on Arma2 it works out of the box. Then on A3 the process is the following (order don't mattter) Open Freetrack and start Open A3 Open OpenTrack and start - you can close it Alt Tab back and enjoy (have to do it at every launch) Note: I use TiR output, I had to increase sensitivity for A3. Be sure to go to ||CONTROLLER|| and hit [REFRESH] if Tir (or FT) don't show up then it's not working for now. COntext: My goal here was to achieve Head Tracking using a WiiMote to offload calculation to the wiimote. Issues here: WiiMote has a quite narrow cone, moreover on 100 fps 55 goes to trash... Batteries at eaten in around few days, so you need a pack of 4. The WiiMote cannot be plugged in the computer without specific hardware. That will require you to use a BlueTooth stack to communicate. I've tried Win10 one (upgraded aswell); then BlueSoleil shareware; then Toshiba one. As you can't pair a WiiMote easily the first 2 are useless. The third one is just awesome. Conclusion: I've bought a ps3 eye instead because of the narrow angle. Even though it is incredibly immersive! I've played hours on Arma2 campaign (thing I never do usually)-

Moveingunner for gunner 2 and 3 pos BMP3
rejenorst posted a topic in ARMA 2 & OA : MISSIONS - Editing & Scripting
Hi I am just wondering what the moveingunner command is for the BMP3 sidegunners. Since the BMP3 has 3 gunner positions. Thanks. -
Since BIS have surprised and delighted us all with the addition of full Freetrack support in the recent beta (pause for prolonged applause) I thought it might be a good idea to start a General Freetrack Thread, where people can share ideas and knowledge about using Freetrack, specifically with Arma2. Hopefully, others will do the same, and newcomers will be able to find out all they need to know here... So - Thanks once again BIS, on behalf of the whole Arma2 Freetrack Users Community!... and I'll start things off with a brief look at my own Freetrack kit and how easy it was to put together... OK - I'm assuming firstly that everyone knows basically how headtracking works - there's essentially two options - active or passive tracking... With Active tracking you wear a clip of some kind with the requisite 3 "spots" being provided by LED's (usually but not necessarily infrared) - that means powering the LED's, that means a battery or a cable somewhere along the line. With Passive tracking, instead of LED's on your headset throwing light at the camera, the camera throws light at you - all you need is 3 "spots" that will bounce that light back... No lights, no wires, no batteries, no cables, no fuss... Freetrack can do either - so can TrackIR, almost... Naturalpoint market a nice hatclip which is perfect for passive tracking, (though you could make one yourself with an old DVD box and a pair of scissors), but you need to wear a hat, obviously... I've got a nice lightweight headset I use, but didn't want a hat, so I wanted a sideclip - like Naturalpoints trackclip - but smaller, lighter, with passive reflectors, because one cable is quite enough to be dragging around - they don't make one (maybe they should, cause as far as I know, nobody does) (do I get a commission for the idea?), so that's where Freetrack and a little "DIY" comes in... Here's my setup... The important bits to notice are the webcam (top right), and note how it's offset from centre, to match the headclip (bottom left), which is worn on the right side... The Cam goes in front of the CLIP, not the wearer... Also notice the clip happily reflecting really well... MUCH more than anything else... that's good... But first, the camera... With Freetrack you can use a fairly wide variety of cameras - almost any webcam you can get some sort of control over exposure on will probably work... however, the framerate may not be great... This isn't quite as important as it is for actual Arma2 itself, but the same rule basically applies - more is better... This is where the newest (and most expensive) TrackIR scores well, and a smooth ride is usually guaranteed. Apparently you can use a Wii controller as a cam with freetrack - I dunno anything about that at all, but I'm told you can get awesome tracking framerates... So if you have one you're already sorted... A stable 30FPS with virtually zero jitter is smooth enough for me so lets take a look at my cam... Its the A4tech PK333MB - a mere £15.51 currently (with free postage) at Amazon UK It's a "nightvision" cam, which means that it has 6 x Infrared LED's ready to throw invisible light in large quantities as soon as it gets a bit of sticky tape over it's daylight sensor (only during gaming - the rest of the time it can be a normal webcam)... Theres a lot of discussion on the Freetrack forums about fitting visible lightproof covers, removing built-in IR filters,etc from webcams - I couldn't get mine open so I just used it straight out of the box - it works fine, and doesnt seem to pick up much, if any background extras at all... Someone asked me about this cam before, and I made (my first ever) deeply cheezy little video to show it working in broad daylight near a window with the 4 x 50W overhead lights on and still show nothing but the 3 reflective spots... here it is (no laughing)... Surprisingly good for a totally unmodified camera - with it's "IR filter" still in place... You can see from the cam view in Freetrack (the big black square) that the camera couldn't see me at all, or anything else in the room - but the 3 reflectors on the clip showed up loud an clear... OK... so that was the camera, what about the clip? Well, firstly I had a good look at the Freetrack Forums where I saw all sorts of exotic headgear, and also found the standard proportions for a clip (which I reduced by 20%)... Here's a closer pic... And here's a closeup of the "clip" part... The "legs" are the legs from an old pair of sunglasses, the "clip" is a cheap cableclip for sticking round the back of hi-fi's and stuff - it came in a big pack for £1, all different sizes - that one fitted the side of my headphones nicely... I used 2, one as it was and the other I cut just the flat base part off - a spldge of glue and sandwiched the glasses legs between them - clamped the whole thing with a pair of pliers and left it to dry... The "reflector balls" are three lightweight cheap plastic beads from an old necklace, roughly covered with a bit of that dull but unbelievably reflective silvery-grey tape you find on cheap safety vests...(poundshop again for them)... There's a wide variety of other hyper-reflective materials you could try... In fact, Naturalpoint used to sell "reflective dots" back in the day when 3 sticky spots on a baseball cap WAS TrackIR! (we all gotta start somewhere, huh?) They still sell them I think, though for my next clip I'll probably look at something more impressive made by 3M. I just happened to have all these bits to hand, you could use almost anything (Telejunky from Arma2base.de has a Freetrack hatclip made out of LEGO! :D)... the first version I made I glued and pressed the "legs" between two small coins... The bottom line is - three reflective dots in the required proportions - the only other limit is your imagination... B PS - A few people seem to be having trouble getting freetrack to work... worked first time for me... I'll repeat the procedure below...
