I have uploaded a model to mixamo.com. In mixamo, I've applied an animation, and in the mixamo preview window, the feet are perfectly stable, they don't skate at all.

I have downloaded the resulting fbx animation together with the skin, and I have opened it up in Autodesk FBX review.

In Autodesk FBX review, the feet are also perfectly stable.

I have then imported the fbx in Unity without changing anything.

In the animation preview window, the feet are skating.

Why is that so, and how do I get rid of it?

  • \$\begingroup\$ @eLTomis I have not applied / changed anything, I just imported it into Unity. Should I provide them anyways? \$\endgroup\$

  • \$\begingroup\$ oh, if nothing is changed, then no - not neccessary. Just edit your question and mention that you kept default import settings. 😉 \$\endgroup\$

I found out that the skating feet were caused by the option "Anim. Compression: Keyframe Reduction" in the Unity Animation tab.

Once I set Anim. Compression to "Off", the skating feet were gone.
