mBlendInTime
F32 = 0 The time over which the joint weights change from the current mask to this mask when
the event starts, in seconds. The change is linear. 0 changes at once.
An animation event that changes which joints follow the
path of the unit. It works on the skin's conform-to-path pose modifier
(ConformToPathRigPoseModifierData in
SkinMeshDataProperties.rigPoseModifierData). That modifier bends a chain of joints,
such as a tail or a long body, along the trail of positions the unit has moved
through, so the chain follows the turns the unit has made.
The modifier weights its joints with a mask. While the event is
active, the mask of the modifier is replaced by mMaskDataName. When the event ends,
the modifier goes back to its own default mask.
Without that modifier on the skin, the event does nothing.
F32 = 0 The time over which the joint weights change from the current mask to this mask when
the event starts, in seconds. The change is linear. 0 changes at once.
F32 = 0 The time over which the joint weights change back to the default mask of the
modifier when the event ends, in seconds. 0 changes at once.
Hash = "0x0" The mask to use while the event is active, as a key of
AnimationGraphData.mMaskDataMap. The mask weight of a joint is how much that joint
conforms to the path. Empty, or a name that is not in the map: every joint of the
chain has a weight of 1.
