Unity Freetrack Positional Tracking

For a proper cam u need a playstation 3 eye($10 used at ebgames, one with rounded lens the newer ones have flat lens and are really hard to take out the IR filter), 3 IR LED's and 2 aaa batteries you shouldnt even need a resistor connecting them in series and you will get longest battery life too. Some people report not having to modify the ps3 cam at all using IR LEDs. myself i have an ARUCO symbol(augmented reality api) on the front of my rift and it does the xyz with ps3 cam while pitch yaw and roll are done by the rift I use Opentrack for combining the two input methods. Cant get it working in my games unfortunately, arma 2 not recognizing freetrack output for some reason same deal in arma 3.
