If it's all that trackIR stuff, I can't follow it.
Same here. But, mine did work so here it is in simple language.
ACRealHeadMotion_freetrack.py - put in your RHMAC folder.
NPClient64.dll - put in FreePIE folder.
Run Real Head program and on the second line click the button and point it to the ACRealHeadMotion_freetrack.py file.
Maybe I got lucky....
