animation export script

Well, I don't really know, but the person who gave them to me said that these models are identical to the ones in Heroes of Might and Magic V in terms of the meaning of various parameters.

Maybe they correspond in terms of the content of the .mb files, but for exporting animations, there are some clips in the .ma files that are unclear what they are for... maybe it's worth asking that person about the .ma files?
Or, less likely, maybe they can explain how to export animations...
