Class : Apprenti Posts : 17 Registered on : 08/02/2013 Off line	Built 3 point clip over weekend, really excited to try it out in Euro truck simulator 2.... However! I have used the SFP485p LEDS, and 5v usb same as in the sticky.... But i have to sit about 300mm from my screen, if i move back the leds are not seen by camera. I'm using a Microsoft VX-3000 WEBCAM. Initially i had 2 layers if photo film over the lens. I removed the photo film and now i can sit about 500mm but it is still too close. How far from monitor do you all sit? The other thing i noticed in both Free track software and Euro truck simulator the head is moved forward a long way. Which is kind of correct, my real head has moved forward, but if i move backwards the leds don't show up. Please help, this looks so good, (if only I can get it to work correctly!)

No I have not removed the IR filter, I was using photo film over the lens. But last night I removed the film, and turned the lights off in the room, so only light from monitor. I could see the 3 LEDs in free track software, but only when they were very close to the camera. Looking at the LED's with just my eyes I can just see them shining a bit red. If I use the camera on my phone they glow bright purple. I will remove the filter tonight and try again. I moved the fresh-hold slider as far left as it would go, until the whole screen went grey. When you say change the exposure and brightness, should i increase or decreade them? ie slide left or right? I made several changes to the profile last night trying to get it to work... I noticed this morning, that the head in free track has moved forward and to the right? Is there a setting somewhere that tells it where the head should be (have i messed it up)? When I press the center button, it always moves the head forward and right.

If you're not able to capture the LEDs without the daylight-filter (film-filter) and high exposure and brightness on the webcam, then the ir-filter of the cam is to strong. To see how to remove the filter: http://www.free-track.net/english/hardware/filter_removal/microsoft_lifecam_vx1000.php another vx-3000 experience: Freetrack with vx-3000 (Disable all auto-functions.) I noticed this morning, that the head in free track has moved forward and to the right? Is there a setting somewhere that tells it where the head should be (have i messed it up)? When I press the center button, it always moves the head forward and right. You need to enter the correct model dimensions and above all the model position: http://forum.free-track.net/index.php?showtopic=3455&message=17852 (Second part).

Then the camera could see the 3 leds really well even when I sat back from the monitor. However the next problem was the size of the LED's, they were massive ! I tried lots of things, moving every slider, changing every value but could not reduce the size of the LEDs.... I even deleted freetrack.ini to reset everything, still the head is forward and left !!!!! Then I turned the focus ring on the camera and the LED's reduced in size and I got 3 green lights in Free-Track. Happy days - now to keep playing with the settings to improve things - Thanks for your help.
