If true, then kinematic objects will be written back from simulation to the bones.
Description
If true, then kinematic objects will be written back from simulation to the bones. This only
necessary when either kinematic targets are being used, or when the target bone differs from the source bone.
When bodies are written back from simulation, if this is set to false, there is a small performance benefit to skipping bodies that are known to be kinematic, and when they are set to just track the input animation.
