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

I figured out the texture issue; I was loading the same textures into different materials in Archangel, so during the conversion, the materials merged into one. Also, here's a funny detail: judging by the skeleton, when loading, both groups and the thing I was resizing became new bones... I didn't even think it would turn out this way... If I were a D&D character, I'd have low intelligence but high wisdom 🤣. I don't understand how to work with the skeleton, but I'm changing it the way I need to.
