Hi, this is Delphinium from Team Froggy&Catty.
I made this to help StarCraft2 modders in making animations with 3dsmax,but it should be helpful to all animators.
This script can help you to transplant animations from an animated character to a new one.
You can use the mocap data, biped animations and so on as the animation sources of your own character, while keeping your custom rigging rulers.
I wish you'll like it and best wishes from China!
