Anybody know? I'd like to know as well. My custom race is supposed to have a Blue home star, and I'd like to know how to change it.

While we're at it, anybody know how to name the other starting planets and not just base them on the name of the home planet?

Thanks, that works, but now we still need to know how to change the homestar color. So far, I've had no luck figuring that out.

Don't know about changing star colors.  Looks like Marvin has that covered.  Changing planet names is easy, though.  Just look at the other custom star systems to see the tags used to designate the planet name.  Just put those tags into your custom system with your custom names and you're good.

You can add more custom systems to the CustomPlanets xml.  I find it easiest to just cut-n-paste an existing one then edit to my desires.  For anyone confused about planet size, texture, etc, it's nice to know that values will be randomly assigned if you don't specify them.  So let's say you cut-n-paste Drengi, for example, but don't want a clone of the Drengin home system.  You can just change the planet names and delete all the texture, size, and other tags to get random values - instant custom system.  That way you can use your custom systems until you figure out more about the textures and such.  Also, planets can have either rings or a moon, but not both.

Nah, it didn't work. I opened StarTypes.xml and added a new entry with the values I wanted, saved, then opened GalCiv and started a new game. Star was still yellow. I placed a copy of the file in the TA Data folder, then modified the vanilla StarTypes file the same way, and the result was still the same, yellow star. I made sure the star's name was exactly the same as the star in my custom system, which does work.

I can't seem to get it to work so, beats me if it can be done.
