Dial "PitchOnOff" can be set to either 0 or 1. PitchOnOff=1 activates the pitch control. The model will move with a tangential pitch orientation along the motion path. This is typically used for vehicles on the road. PitchOnOff=0 deactivates the pitch control. The model will move with a constant pitch orientation. This setting is maybe useful when you have a walk along the motion path.
