Why does the procedural generation suddenly makes clusters of a specific class of stars?

So I'm on my way to Amundsen's Star and while traversing the Eorld Phoe sector I found a relatively flat layer of L, T, Y and proto stars. The name tag of all of them suggest they aren't hand placed but a result of procedural generation. Have you guys seen anything like this?

You are in the brown dwarf slice (many other names for it).

It spans across the entire galaxy at the Y co-ordinates of around -25 to -50.

Sectors can however have a lot of a certain star type, like giants for example. I think it's divided into cubes rather than sectors though.

Thanks for the info, +rep

To piggyback on this thread,


Does anyone know if the procedural generation algorithm produces adjacent or nearby systems with similar content?

I've been exploring systems in an area where a lot seem to have no planets. I was thinking RNG had me by the tail, but this thread caught my eye . . .

I think these are all things you would expect in the galaxy. Stars that formed in areas where the stellar nursery gas cloud was diffuse would more form without planets, whereas planets formed closer to the center of the nebula would more likely have planets. As regards large layers of stars, the galaxy would have gone through several stages of development, our sun is probably a third generation star, first generation stars would be a far older and exist in layers toward the center of the galactic disk, as stars explode and seed the galaxy with heavier elements that form planets their remains would form a compact layer of dwarfs and neutron stars in a more spread out galaxy.

Thanks for the quick reply. Yes, as it pertains to actual galaxy and localized stellar evolution, that's how it -should- work (except 1st gen stars are gone). Was wondering to what degree the procedural algorithm does so.

Thanks!

Anyone who's been out exploring has experienced it: sectors which seem to be "barren", or sectors where certain planet types seem to be far more (or less) common than elsewhere.

I've seen a sector where gigantic (10-plus Earth masses) Ammonia Worlds seemed commonplace.

I've seen several sectors where practically every star system I jumped into was a binary with no planets.

I've seen a "dry" sector where waterworlds and ELWs seemed much much harder to find than elsewhere.

Yet, we still don't really know if there actually are "sector biases", or if it's purely the randomness of the galactic seed. To find out, you really need to do some thorough surveying of entire sectors or subsectors, with seriously large sample sizes.

Thanks ever so much!

This is just my second trip into the deep, the first being a 12000 ly one. It was pretty linear, so had never sampled a good number in a relatively compact volume.

what about star clusters in perfect cubes...

That's almost certainly a hand-placed cluster, based on imported data from real catalogues. Since they only import data for a certain block of space, it looks strange - in reality you'd have smoother changes.

No, the "cube clusters" aren't hand-placed stars. You can see that it lines up perfectly with the galactic plane, so it follows the procedurally-generated boundaries for galactic sectors, which are in line with the galactic plane. They're "cubes" within which procedurally-generated B type stars, which can be seen from quite far away, are more common than in neighbouring regions.

It's probably not an entire sector; sectors are divided up into subsectors based on mass class and each subsector has different probabilities of B type stars forming. You've found one subsector that has a high proportion of B class stars.

Yes I think I remember reading that somewhere, sectors of the galaxy are procedurally generated in cubes with star population generated across the cube based on the average density of the region, so if you happen to have two neighbouring regions with a large difference in density, which I suspect is quite easy to occur, then there will be distinct boundaries between the regions, hence the strange cubes.

Oh yes and as to stellar evolution, I believe also I remember one of the devs discussing this, the galaxy seed is evolved from the birth of the galaxy through to the galaxy we have today, it's never going to be perfect because we don't really understand everything about the universe and what factors affect galaxy development, but it appears to have done a damn good job, there are always going to be anomalies like the one mentioned above because we don't currently have the computational power to evolve the galaxy down to the level of individual stars, maybe one day!

i also have seen a small cube within a larger cube, the larger one (was a sector) not as distinct but still obvious so entire sectors can exist too

there is one cube sector I know of and about 4 mini cubes within sectors, but I haven't travelled everywhere so there are probably more ;)
