You can write your topic however you want, but you need to answer these questions:

  1. I want to animate wings for a friend

  2. ** I once saw a Devforum post about a fire hydrant that was animated and it bent. i need to find this post to see how to do it and make animating extremly easier**

  3. i have no idea where to find this post

If you have a link or can show me how this works, please comment. thanks you
