Well a red background is quite possible. As is a red nebula, but seeing as how this system is sitting smack dab center of the Barrier ice field, logic would dictate that it be a light shade of blue. I don't plan on messing with the background too much. I'll probably cut and paste Manchester for that information.
In other mods I have noticed that the developers have combined bits a pieces from other 'planets' and cut and pasted them onto each other. I believe this was done with code. I know FLE wont let me do it, but if I can dig the info up needed, I believe I may be able to combine the city scape from Cadiz or Vogtland, mix in the one from Kyoto for extra buildings and change the background to something dark and outdoors, like Pitsburgh's. If not there is always the fall back plan of using a large pirate asteroid base. Not all moons are round affter all.
There is also the possibility that these are 'kit bashed' models. If that is the case, some of you ship wrights may expect to find me knocking on your door if I can dig up how to do this. This is all future planning anyway, and until I get a system together that dosen't crash my FL server, is merely me talking.
Examples of what I am talking about. (Crossfire mod)
I only make this declaration of intent because I have spent the time since the original idea proposal looking into the various aspects of moding FL. In fact 90% of my reason of posting this was assurance that I see this through, I will have people kicking me in the butt to the finish.
As far as free time, I am 20 year old male working one 20-30 hour a week part time job. I have the free time if I choose to apply myself.:)
Anyway, I skip that second idea for right now because the more I look at it, the cooler it seems but it is very far flung in terms of execution. I have allot more to learn first.
