Remarks
Generates the RootMotion for this Source, can be used for both "live" generation or for playback (client prediction correction, simulated proxies, etc.)
Examples:
- Animation RootMotionSources use Time as track time into AnimMontage and extract the root motion from AnimMontage chunk of time (Position,Position+DeltaTime)
- ConstantForce source uses Time as the time into the application so if its duration ends halfway through the frame it knows how much root motion it should have applied
- Spline/curve-based sources use Time for knowing where on spline/curve to extract from
