ProMods

I started learning and making my map of Ukraine, and I want to make it as ProMods plugin(addon), so it will require ProMods. How can I do this and can I use assets from promods map. My map will be free.

You need to edit europe.mbd and only save the sectors you work on.

I know that I need to edit europe module, but this map will require Promods, because original game and Going East DLC don't have border with Ukraine. So I need to make it as Promods plugin. Because of this I ask that can I do this and how to do? Do I nedd to put promods files in mod folder and do all with installed promods.

Yes. Place our files in your mod folder and edit the map then.

And I can post this map then in public acess. And what about using assets?

If you use our assets, players will need ProMods in their mod folder to use your map.

They'll need Promods in any case, because I'm going to expand promods roads. This mod will be like Project Balcans, as addon to default promods. In this topic I wanted to find out legal point of this.
P.S. Sorry for my English. So I can use your assets and expand your roads without any legality problems.

If your mod remains dependent on ProMods, then yes.

And from what city are you going to start?

From Lviv region. I wanted to start from M10 road(throught Krokovez, Yavoriv, Novoyavorivsk and then go to Lviv), but there aren't some Polish cities on this road. So maybe first road will be M11. On it I only nedd to build a small part of Polish road, and then build Ukraine road M11 throught cities Mostyska, Gorodok and Lviv.
