So after reading a bit here and there on creating a custom starting world I've had some success but not complete success.
I'm able to get the system to show as a selectable starting system but it crashes during galaxy generation.
I have used the basic Sol system for a starting template, and modified it to fit the Corusant system From Star Wars. I limited it to 6 planets and opted to try and keep it simple by using art assets from other in game planets.
I modified the StarSystemDefs.xml and PlanetDefs.xml and placed the modified files in the Mods folder. The PlanetDefs.xml only has the modified system info in it and has been renamed PlanetDefs_CorusantMod.xml. I used Skukkuk's Extreme Planet Mod as a base to build the system and planets. But considering I used existing artwork I did not think I would have to modify the ContinentDefs.xml or PlanetArtDefs.xml files. The modified parts are listed below. Any help I can get on figuring our what I did wrong would be appreciated.
