This script allows you, in five man minutes, to make a entire leg rig, bones and controllers. The five minutes are mostly to get the correct joints position. It is still a work in progress, the goal is to have an entire humanoid rig in it, and to have other tools for "game ready" rig deployement. It is as close as I can get to a magic button. The sources are available on demand.
After you have downloaded one of the scripts below, drag it inside 3ds max, go in the menu Customize, in Customize User Interface... them go in the Toolbars tab, under the Category dropdown, and get the Anthony Roy category. Select and drag the script to one emplacement in your toolbar. You are now ready to use it.
