Import Animation from Mixamo Problem

Hi ,Im new to UE4

I tried to import animation from Mixamo, but it appeared wired.

Does anyone know how to fix this ?

Sorry to be the bearer of bad news, but some Mixamo animations do not use root motion and don’t even have a Root bone AND are a pain in the butt to use without modification.
If you have the option to export those animations with Root motion through Mixamo, you should do that. Most animations don’t have that option though.

If you retarget these to the UE4 Mannequin directly (which does have a Root bone), you’ll have the problem you show in the video where translation information on the Hip bone needs to be used to drive the Root bone, but Persona won’t like it.

You can visualize this by selecting ‘Process Root Motion’ from the ‘Show’ menu in Persona. Make sure you enable Root Motion on your animation sequence.

To fix this, you can either use something like Motionbuilder to retarget and move relevant Hip Translation data to the Root bone on UE4 Mannequin.
OR if you don’t want to do that, you can export the retargeted animation from UE4 to fbx, import it into Max/Maya and move the Translation data for the Mannequin’s Hip to its Root.

Some Mixamo animations are really messy in that the characters end up facing a slightly different direction at the end of the animation instead of facing the direction they were on Frame 1.
You need to clean this up in your animation software.
