Guide on adding a new model, animation, and creature to HoMMV

Even better news: using the asset studio program, it is possible to extract models with a skeleton and skeleton binding from the game Might & Magic X: Legacy. Also, some animations can be extracted. Animations are exported smoothly from one archive, but give an error from others. Perhaps the problem can be solved. Perhaps not. In any case, even without animations, these models are useful because, having a skeleton and a configured binding, they can be relatively easily transplanted onto some skeleton from Heroes 5 or Heroes 6 and used with animations from there.
