If you want to edit the map in-game, be sure to load the primary plane (first on the list that appears), and not plane_2, _3, or _4.

However, the in-game map editor is only good for modding connections and terrain types. You cannot add units or magic sites in-game. Plus, saving any changes in-game will re-write the file and eliminate all customization in the map files - tens of thousands of lines of code that sets indie defenders, starting locations, custom magic and throne sites, and pretty much everything that makes the mod and map what it is. So unless you have a plan and know what you're doing there, don't use the in-game editor.

I think what you are looking to do will require going into the map file with a text editor (Notepad++ is the best). If you are reasonbly savvy, you should be able to figure it out what you want to do from the context of what is there already. The map modding manual is a great resource, located on the Illwinter website. And the dom 6 mod inspector (google it) is your friend.

Or share what you're looking to do, and if it makes sense, I'll be happy to work it into the next update.

I'm looking in the mod folder, and I can't find a .map file. I'm trying to set fog on, because I think it would be cool to explore as I have no knowledge of the Forgotten Realms and it seems huge as hell.
What file should I be editing? I'm pretty sure I need to add a mapview = off or something like that (I forget but will look it up once I know where the right file is)

You'll need to head to your \AppData\Roaming\Dominions6\maps folder and find the ForgottenRealmsUnderdarkExpanded subfolder. In that, you will find the .map file.

I believe you would add "--" *(as in two dashes, not the quotes, on line 18. #mapnohide. So it should look like:
--#mapnohide

That should add the fog back in.

that worked! TYSM
