I see! Ok, I will segment it into some natural parts
In the next step now, I will connect/link the bones to each other properly, weight them to the mesh and then segment, and then look at the hierarchy. Then I will export and see if it works in game simply as a *swoop* with no animation. If all goes fine, I will start animating it, and seeing if I can get it to both walk, run and fly and so on.
Thanks a lot for the help, but I can't promise I won't have quite some more questions
