mClipName
Hash = "0x0" The transition clip, as a key of AnimationGraphData.mClipDataMap.
A blend table entry that puts a transition clip between
two clips, for example an Idle_In clip between Run and Idle1.
When clip A plays and the game plays clip B, and the entry for (A, B) is a
TransitionClipBlendData, the client:
The step from A to the transition clip and the step from the transition clip to B each
use their own blend table entry, or 0.2 seconds. B starts that long before the
transition clip ends.
If A and B name the same sync group, B starts at the time that A had when B was requested.
