So i've taken a unit and imported it into 3DS Max, altered it's mesh and now i need to rig a skeleton to it to get it back into the game. However, i'm not sure how to do this for Medieval 2 TW. Do i have to put the model back into Milkshape to get the skeleton in, or can i import the skeleton into 3DS Max and do it in there?

All help would be greatly appreciated!
