Hello all,
I’ve been wrapping my head round MotionMatching but unable to find much information on the PoseSearchBranchIn notify state.
That said from what little I have been able to glean it seems it’s only needed if you intend to manually select an animation using state machines, etc, rather than letting the MM system doing its thing? (Example Comment)
Just wanting to make sure before I move on from it as it isn’t something I intend to do.
Thanks
Alan
Does no-one know? 
It’s not for “manually” selecting an animation.
When you add this notify state to your animation sequence, you add the animation to a list of relevant animations for a Pose Search Database, and then when Motion Matching is called, the frames covered by the Notify will be evaluated by the Pose Search Schema and related channels.
You’re pretty much saying “Hey, this stop animation should be in the database, and I want these frames to be evaluated during motion matching”
Thank you, that aligns with what I was finding with my testing but confirmation is always great!
