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

Let's continue here. I might have sounded a bit harsh, but it's just because I'm disappointed that the model won't be able to be part of the game... Psatha, I'm not a 3D expert at all, so I can't say anything about its versatility, but I made a very simple model and essentially added a very simple skeleton. What's not supposed to work there? I baked the animation as I was explained before, to get rid of the rigging helpers, and only the bones remained... When I was modding Attila: Total War, I tried to import new models (just for testing) - it worked... normal export, without errors... But here, as it's written in the manual, it's from one program to another, from another to a third... and you want to say that there can't be any distortions at these stages? It seems strange to me, honestly... Maybe there are some specific pitfalls for this particular game. Added after 4 minutes "Since the game uses animation in Granny format, it is indirectly linked to the skeleton... and in some cases, the skeleton file (which is also in Granny format) can be changed." But this is even less clear to me - if you change the skeleton, how will the animation work? Animation is essentially a skeleton that has movements and bone rotations... therefore, it's obvious that they should be the same
