In the past i have made some 'spectator pov' camera sets for a couple of tracks, and it was always a pain in the a** to find the exact XYZ coordinates for a new track camera. (till now always used a work arround with the car itself to get the right coordinates, but it took ages)
Now i can use the freecam in this app to go to the sweetspot for a trackcam, copy the YXZ in my cameras.ini file of concerning track. It saves a lot ot time making this camera sets in the future. Not even used this app for its main purpose, but its a big help by making good track camera files.
