Current questions and answers regarding the map editor.

What if the creature is an NCF file? Can you explain it with screenshots, because I don't know where to find these things?

It depends on what you're interested in. I have a mod installed for the creatures of the Unicorn Empire, as I have the campaign of the same name installed. I suggest you go to the thread about this campaign on the forum, download the NCF_EU_Creatures.pak file, and take a look inside. All files related to the new units are located inside.
