exporting and rebuilding in unity or other engine

[3-d]

so im wondering if anyone has any clue how much work getting a skyrim character exported, rebuilt in like blender or unity. im using nothing vanilla so I assume my downloads folder should have all my body meshes faces clothes hair etc etc , I may even be able to rescue animations ?? im hoping to re rig my "avatar" so can animate her in better engine as im over the same set of animations
