Build 0.991.49.2090: The Universe Generation Update

[p]Hey folks![/p][p]Our next major patch, 0.991: The Universe Generation Update, is now live! This update brings major changes to SpaceEngine’s procedural generation systems, elevating all things beyond the known universe and breaking from the dreaded giant-terra-giant-terra pattern.[/p][p]Generation changes like this cause a universe reset— recalculating the 'where' and 'what' of all procedural objects. For established users, this means information like screenshots, saved locations, and procedural object names from 0.990 will likely no longer be accurate*. Fear not for your 0.990 records, however! For posterity, build 0.990.48.2075 has been saved as a legacy branch and is available in the Betas dropdown (Steam library, right click SpaceEngine, Properties, Betas).[/p][p] (* data from Beta Update 2 will carry over)[/p][p][/p][p]The changelog section at the bottom outlines everything new to SpaceEngine in 0.991.49.2090. Below we’ve highlighted some of the immediate changes you’ll find in the update:
[/p][h3]Planetary Generation[/h3][p]In 0.991, expect system-to-system exploration to become more interesting! The old giant-terra-giant-terra meander sequence has been replaced with a more diversified procedure. This includes dwarf planets, which did exist in 0.990, but were exceedingly rare.[/p][p]Comparison of the 'same' system between 0.990 and 0.991[/p][p]
You’ll also find greater diversity among planetary rings (including rings for smaller objects like dwarf moons), accretion disks, and more![/p][p][/p][h3]Graphical Tweaks[/h3][p]We’ve also made some tweaks to visualization for star surfaces and underwater terrain.[/p][p]Sunspots and granulation patterns in 0.990 had contrast much higher than in reality. With this update, they look closer to real-life images.  On top of that, we’ve updated calculations so that the visual temperatures of these features are determined by the effective temperature of the star.[/p][p]A comparison of granules and sunspots on a G2V star in 0.990 (left) and 0.991 (right).[/p][p][/p][p]Also new with 0.991, the terrain of underwater surfaces mimics the absorption of light, darkening as you increase depth. This is a small shader change, but lets you feel just how far down you’ve gone.[/p][p]Sea floor images from a variety of depths, showing their appearance in 0.990 (left) and 0.991 (right).[/p][p][/p][h3]Math Overhauls[/h3][p]Finally, we’ve updated the math for several aspects of procedural generation. We’ve already mentioned planetary generation and sunspot temperature, but that’s far from everything! We’ve also overhauled the math behind:[/p]
  • [p]Globular cluster generation[/p]
  • [p]Effective temperature/radii for main sequence M dwarfs and L, T, and Y brown dwarfs[/p]
  • [p]Mass-radius distribution of terrestrial planets[/p]
  • [p]Iron core mass distribution in terrestrial planets[/p]
  • [p]Eccentric orbits (greatly reducing the likelihood of planet/star or planet/planet collisions)[/p]
  • [p]Galaxy type generation probabilities[/p]
[p]
For those who want to read more, see the Overview article from September [/p][p][/p][p]What you don’t see here is all the hard work that went into fixes and testing during the Beta, both by the team and you, our dedicated community. We opened to Beta on September 15th; then, over the course of two months of daily feedback (and three total resets), we’ve packed in several further fixes to make this the best build it can be, as well as logging many more reports and suggestions for the next major update.[/p][p]It’s all thanks to you, our community of space enthusiasts, that we can keep working on this project. We’ve made a solid leap with 0.991, and have much more planned for future updates. Thank you![/p][p][/p][h3]Changelog:[/h3][p]Editor’s Note: Changelog reflects changes between 0.990.48.2075 and 0.991.49.2090. Fixes between beta patches are excluded. Duplicate entries from beta patch notes imply the issue(s) pre-dated 0.991.[/p]

0.991.49.2090 Public Beta Update

[p]Hey folks![/p][p][/p][p]Today's Beta update brings you the second (and tentatively final) wave of fixes that affect generation, meaning yes, the universe will be resetting once more! Our focus is on fixing bugs introduced with 0.991, specifically, as well as addressing issues with generation that we can incorporate without overexpanding our scope, and miscellaneous/normal operations items, such as new exoplanets.[/p][p][/p][p]The goal from here is to clear 0.991 for Public branch release. We still have plenty of ideas for improvements down the line, though, both internally and based on your excellent suggestions![/p][p][/p][p]Like with the previous mid-Beta update, the primary place for discussion is in the dedicated 0.991 channel on our Official Discord![/p][p][/p][h3]Changelog:[/h3]
  • [p]Fixed C-Hd stars having too low mass.[/p]
  • [p]Fixed a bug where star age could exceed lifetime for systems with a stellar remnant.[/p]
  • [p]Fixed a bug where binary planet orbits were often oriented on-edge, “cartwheeling” around their host stars.[/p]
  • [p]Fixed a bug where SpaceEngine would crash if you changed the obliquity of a binary planet barycentre in the planet editor.[/p]
  • [p]Fixed a bug where comets and asteroids were assigned temperature classes that were too hot, and moons were assigned temperature classes that were incorrect. Classes for all planets/moons/comets/asteroids are now based on their time-averaged distance from their host star(s).[/p]
  • [p]Fixed a bug where every solo star (ie: not in a multiple star system) had the same axial tilt of 100.28 degrees.[/p]
  • [p]Fixed a bug where changing the oblateness in the Planet Editor was not reflected in the Wiki.[/p]
  • [p]Improved orbits so clipping between planets and stars is much less likely.[/p]
  • [p]Fixed a bug where rings around dwarf moons were intersecting with their moon.[/p]
  • [p]Fixed distance to Centaurus A*.[/p]
  • [p]Fixed display of Quaoar’s name in the system browser.[/p]
  • [p]Updated the exoplanet catalogs with 9 new host stars and 16 new planets.[/p]
