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

Comrades, I have a problem: when replacing a regular peasant with a new creature from version 7, everything works perfectly. But when adding it as a neutral unit on the base of an NCF, the assigned abilities disappear (the stats remain correct), and the selected camera also doesn't work – it displays the camera for the "Yeti" instead. I added the creatures in the same way as in the Zahar0z mod. Maybe this isn't the right section, but let it be here anyway. Thank you.
