Leg right IK bone acts strange [FIXED]

I’ve just imported my animations from blender and noticed that walking animations looks strange. My right leg on some keyframes just transform in strange way, it works fine/smooth in blender. Any idea what that may be?

Of course I’ve imported mesh with skeleton so it should be fine right?

Looks like this community forum is dead, but I’ve found solution :slight_smile: My bones were too “erect”, I’ve lowered pose and it works perfect.
