How does the skeleton system work?

[chess007_phoenix_clan]

As most units are human, and from what I've read so far, it seems like units are made up of a skeleton which is skinned and has anchor points for objects. What format are those skeletons in? Would it be possible to add a non bipedal, non human unit? I'm not asking someone to do that for me, I'm asking because I'm interested in modding. Thanks.

The meshes and animations are in the standard COLLADA format (except for some old ones which are PMD/PSA). The file binaries/data/mods/public/art/skeletons/skeletons.xml defines the skeletons that the game can load, and the mapping from the bone names in the COLLADA file onto those skeletons. You can add any new skeleton shapes into that file - the game just requires that when you use an animation with a mesh, they came from the same skeleton.
