hey, Is there any way to bake the imported FBX bone animation into a curve asset? thanks

Try an Anim Modifier , you should be able to extract and bake the curves from joints.

Yea no. But you can open the bone path up in a DCC, copy the axis value you are interested in into a curve, bake that curve to an animation ( UE4Curves : Unreal Animation Curves from/to Blender ), import the animation to unreal, open the curve, copy the points, create a curve asset, and paste… In sh…
