After importing my animations from Blender to UE4, there is a strange twitching in the feet of one of my animations

I had a similar issue. The animation looked solid in Blender, but feet sometimes shifted slightly in UE4. It was caused by the FBX export. Setting “Simplify” to 0 in the Animation category of the FBX export options solved the problem for me. You could also try changing the “Sampling Rate”.
