How do I add a hero to the map editor?

1. Open the advanced map editor, select View => Game Database => New Window, then Resource => Select Tables => Select All, then Resource => New MOD => Enter the name and description. You can now start making changes.
2. Go to the advanced map editor, place any hero on the map. Select him, choose the parameter AdvMapHeroShared, create a new one using New, for example, TESTHero.(AdvMapHeroShared).
3. Click the three dots.
4. A window with the hero's parameters will appear; configure the following:

Model,
AnimSet,
Active tiles => Add => x=0, y=0,
ObjectType (any),
Icon128,
InternalName,
Class,
Specialization (Name, Desc, Icon),
Face Texture and Face Texture Small,
HeroCharacterArena and HeroCharacterAdventure,
CombatVisual,
Town Type,
Editable => + => Configure as desired,
Selection,
Trace,
Hide in editor => false.

To add your own icon, where a new one is needed, create a new texture Icon.(Texture), select the icon file in Scrfile, set the parameters Type - TEXTURE_2D, Conversion type - CONVERT_TRANSPARENT, Format - TF_8888, Instant load - true. You can also choose icons from others.

You can do the same with the model and .(Character): either choose from existing ones or create everything yourself.
5. Resource => Pack MOD.
6. Go to the game folder; there will be a "map" NAMEOFMODFROMPOINT1.h5m; manually rename it to MYMODENAME.h5u and send it to User MODs.
7. Done.
P.S. I have already attached screenshots; everything is clearly visible in them, and this confirms the functionality of this method.
