I followed the manual, added a new hero to AdvMapHeroShared, and specified the path to him in AdvMapSharedGroup in "Academy" and "Any". This is to ensure that the game recognizes the hero.The only problem I encountered was adding face textures, so for testing purposes, I used textures from Or.
I launch the map, and the hero is not there.
Honestly, I don't know what else I need to do because I followed the "guide."
UPDATE: The file appears in the editor in AdvMapHeroShared, but the hero is still not in the game.
