I have pics for everything. As for sharing systems, for my Kuja race that I'm trying to build, they have their own starsystem, with stars and planets named differently and unique, following the structure of the corresponding file (StarDefs, PlanetDefs, StarSystemDefs, etc).
The interesting thing is, if I place all my modded xml files in the program folders (with the exception of StarSystemDefs_Kuja) and I copy the <StarSystem>My entries for my race</StarSystem> into the program file StarSystemDefs.xml, then the game loads, the race shows up. However, if I try to place these into the mod folder, each file in the folder corresponding to the main files locations, then the mod does not show up.
This thread has couple distinct issues going - 1) mod not appearing, 2) StarSystemDefs error. I'm going to start a separate thread to deal with the mod not appearing and use a different case to illustrate. Then this one can focus on the StarSystemDefs error.
(in the end, I'm going for an aquatic race... but this will take time particularly as it pertains to the use of planet tiles and all that...)
