Does the influence slider of an IK constraint in Blender export well to UE4?


The Question is quite straight forward I think. In Blender when you add an IK constraint to a bone, you can set the Influence of it anywhere between 0 and 1. And I was wondering if this Exports well to UE4.
And if not, maybe a slider in UE4 exists to change the degree of effect an IK solver has on specific bones?

None of constraints do export to UE4. You need to set it up once more inside of UE4, but of course the result might be very different. When you export animation, all bone locations, scales and rotations keys are getting baked. Thats why you should pick the bones that deform the mesh tick the “Deform” window and export only them.
