P.S. I think the minimum number of animations required for Heroes 5 has already been created... First, we need to complete another important task. Whether it will work or not is another question. We need to combine all the animations in 3D Max and debug them – that is, refine the endings and transitions between animations to avoid jerks and other issues...
PP.S. Will anyone be able to implement all of this in the game later, as a mod?
