A short 13 minute primer to getting very basic motion matching working in Unreal Engine 5.4 while we all wait for that awesome sample project with the 500 animations!

There seems to be a strange pattern in all the motion matching tutorials that could be misleading or maybe i’m missing it.
You don’t need to check root motion and force root in order for it to work all that does is enable root motion ONLY when you set “Root motion from everything” in the animbp which no one seems to be setting.
Instead now it uses the capsule movement coponent and walking speed to move the character.
It can work both ways so long as you set it correctly depending on the requirements.
Motion matching still has trouble and lack of control at first glance of having characters play their Pivoting animations correctly or their stopping animations. Make sure to provide both left and right foot animations in the processing for all animations that require stopping or pivoting. That could help avoid jitters and snaps.
I would wish Epic integrate an automatic “mirror animation” function somewhere to quickly be able to mirror those leg motions and poses when needed, especially now it could be very useful for motion matching.
There is mirroring of animations for motion matching
There is a “Mirror” checkbox in Motion matching I didn’t dive into it deep enough, but I did give it a quick go with no results. If this is what you referring to and you have a working workflow feel free to share it.
Usually I would expect to create a separate Mirrored Anim file and feed it into Motion Matching as its own Animation.
So far without plugins I haven’t found anywhere in the Engine we can Mirror animations.
Not sure if you solved this yet, but I found there’s a option to enable Mirror Data Table under Skeletons and Index inside the detail tabs under the Pose Search Schema under Motion Matching.
Then enable both mirror and normal in the Pose Search Data Base. Works for me, hope this helps.
Hi i agree, in some of my tests when i disabled root motion it broke motion matching so i just stuck with it on but id love to dive into this with you, much appreciated
Can you share what setup and settings are you using for root motion locomotion with motion matching? All I can get is a jerky movement and motion matching being very indecisive switching between unrelated animations when I enable root motion from everything.
