Blender animation looks different when imported into Unreal

I made an animation where only the hip moves and the limbs are held in place by IK. As you can see, the feet stays in place even when the rest of the body is twitching.

But when I import the animation to Unreal, the feet are no longer static.

Do you know what could be causing this?

Hello there @addygrh!

Indeed, this sounds like the usual Unreal and Blender conflict. These two don’t have the best relationship, specially with animations.

The usual approach that’s followed around the community, would be to reset export/import settings in both UE and Blender, in order to rule out any conflicts between either configuration. Also, please make sure that any transforms and/or modifiers are implemented before transfer. After that, test importing your mesh again, and see if the legs animate as intended.

If the issue persists, please test the method detailed here, I have found it useful for similar scenarios.
