Creating your own Starting Systems

[Neutralista]

So in the customization, you can select a specific starting system: The only two being Deneb and Sol. I remember them going over how to make your own star system in the modding section of the Launch Stream. First: Can someone get me a time code on that portion of the stream? And second: Is it possible to make a Ringworld system? And third: How do we allow this system to be selected as a starting system but not necessarily appear randomly placed during gameplay?

You will have all what you need here :
C:\Program Files (x86)\Steam\steamapps\common\Stellaris\common\solar_system_initializers\example.txt
You will be able to made a ringworld system.

its not harder than other modding, you can download the better sol system mod and use it as an example ^^, ive already have made an custom system for me (sol with a terraformed mars as homeworld, and an tombworld earth)

with some training you can make double starsystems^^
