Greetings, I am a traveller Galaxy master out of ohio. I use CC3 to map things like subsectors, planets, star systems and spacecraft. I am willing to do basic things upon request (subsector, planet and star system maps), however as I use CC3 they will not be as beautiful or complex as you can get from a more experienced user.
Welcome to the Guild xevus! There is at least one CC3 guru here who can work wonders with the program, so artistic CC3 maps are possible. At any rate we have a "Map Requests" section for people to post up commissions. So if that's what you are interested in you might want to head over and check it out.
