I was the one who has build the starspheres. They are not vanilla ones, they are not what was released with Freelancer and they do look different than vanilla starspheres. It is not possible to simply raise the resolution of something and expect that it looks better… it is required to invest alot more work to rebuild something (in order to keep the original style of the system) in a more detailed way.
But still that is not vanilla stuff.

Ill show you what you get when you just change the resolution of something…

You take this as source:

and change its resolution with the result of getting this:

Is that better? Is it an improvement? You can not simply change the resolution of something and expect that suddenly details appear that where not there before. That is just impossible. And just because we tried to keep the original style of the systems it does not mean that we are using vanilla stuff.
