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

It's a pity that the necklace is missing, but what can you do. By the way, Kaspar's animation, even on horseback, is not very good. Besides the usual stance and movement, there is only one decent animation where he flips through a book in his hands. The rest are rather vague. He's jumping on a horse, waving his hands. Plus, for some reason, they didn't make flags for the undead heroes.

In general, I think that if someone wants to port these heroes to the fifth game, the best thing to do would be to put them on the skeletons of the heroes from the fifth game. This would allow them to use the animations from the fifth game's heroes. This would also solve the problem with the effects.
At least, it would definitely be better for Kaspar. As for the others, you need to look, figure it out.
