Stellar density doesn't change in IC 1101

Hi,

I was just wondering what's going on with the stellar density in the center of the largest galaxy, IC 1101? As a comparison, if you go to the core of the Milky Way, there are about 450 stars within a 10ly radius sphere around you (not including the Kern in the center - measured using the search function, set to 10ly). I would have expected that the very core of the largest galaxy in the game would have a mad density of stars, somewhere over 10,000 in the same volume, but it's much much much more sparse there. There's less than 3 stars in every 10ly radius sphere!

And it's not because it is elliptical - go to another elliptical galaxy and you'll find 700 stars in that volume in the core. I would very much like to know why it is like that. 

In fact, to be precise, the stellar density seems to be completely uniform throughout the entire galaxy. I assume this is because it is a non-procedural galaxy. 

Does anyone know how to make a mod that would make this more realistic?

I think it is because IC 1101 is so huge that simulating an accurate number of stars in the galaxy is impossible or something like that :)

Highly doubt that ^

Xoran is right. SE has a limit of number of stars per octree quad, and limit of an octree recursion depth. All this leads to limited star density in a very large galaxies.

Ok fine. Is that a permanent limit or do you intend to change it? Is there any way to get around it? Does IC 1101 really have 150 trillion stars?

 Adding more precision to the calculation, or implementing some a k-d tree mechanism wouldn't fix that issue? Or just fixing the optimization of the current algorithm, therefore the model could feasibly put more stars in an area?
