•The animation layer
overrides the animation of any layer that
contains curve nodes that control the same FBX properties and that precedes it in the animation stack.
•For example:
AnimLayerA and AnimLayerB are both in Override mode. The X translation value for an FBX object
on AnimLayerA is 10, and on
AnimLayerB X translation has a
value of 15. In the resulting animation, the FBX object will have a translateX value of 15.
