I've been wandering around the universe looking for the aforementioned new huge easter egg and have found no trace. of it, or of any old ones for that matter.
This thread is pretty old, and if I am not mistaken, this referred to the version 0.95 of SpaceEngine and the 'Cyrannus system'. ("The twelve colonies of Kobol")
It existed in version 0.95 and 0.96. Not available in later versions.
I've adapted it for SE 0974.
I have made only minor changes.
1. the parameters for life.
2. I have made the composition of the atmospheres for all inhabited planets just like the Earth.
3. I have made a Barycenter for Ragnar and its moon, because otherwise it does not work properly for some reason.
And I changed the order of the objects in the script to make it more manageable.
To use it, extract the zip file to the 'catalogs' folder and add to the 'universe.cfg' under
Star Catalogs // stars catalogs
"Catalogs / stars / CyranusBC.sc"
Planet Catalogs // planets catalogs
"Catalogs / planets / Cyrannus.sc"
