How do I make a custom scenario mod like SW Fallen Republic?

[Nexxarian]

SW Fallen Republic is an amazing mod and it’s the closest thing to what I’m looking to do. I’ve been wanting to do this for a while, and though I think aspects of what I want are beyond my capabilities (I think I would need a team to fully achieve what I envision, I would at least like to make a custom galaxy map and have many preset empires to populate it.

So where can I begin?

In general, download a mod that does what you want and look at how it does it.

If you're completely new to modding, there's a lot of information about modding here:

Modding - Stellaris Wiki

stellaris.paradoxwikis.com

For custom, static galaxies, there's a tool called StellarisGalaxyGenerator by Retalax, that helps greatly with setting up the general shape and framework of the map.
See: https://forum.paradoxplaza.com/foru...tellaris-static-galaxy-generator-v0-9.951308/

It's a lot of work though, and some of it is relatively advanced. Not exactly a project I would recommend to a new modder, but that's your decision to make.
