Disintegration Update | Alpha 19 | Now Available
Nov 8th
Run Steam to update to Alpha 19, or buy Universe Sandbox ² via our website or the Steam Store.
Please note, this is an update for the desktop mode only. We will now be focusing on an Alpha 19 VR update. In the future, these two modes will be merged and won’t require separate updates.
In Alpha 19, simulations are more dynamic, realistic, and exciting. Why?
1. Tidal Forces Now Tear Apart Planets
When one body gets too close to another body of higher mass, tidal friction will begin to heat it up. And if it’s close enough, Roche limit fragmentation will tear it apart, leaving a trail of fragments.
A major theory for the formation of Saturn’s rings is that the rings were once a moon orbiting Saturn, before its orbit took it within the Roche limit and it was torn apart.
Home → Open → Physics tab
Home → Tutorials → 11- Tidal Forces
2. Planets Are Now Vaporized by High Temperatures & Supernovae
Whether by a supernova or extreme tidal heating, bodies now lose volatile material as their temperatures rise. The required temperature and type of volatile loss factors in the body’s material composition and mass.
There are also new visuals for supernovae, and their appearance varies based on the type of the star.
3. Improved Performance, Appearance, & User Control for Particles & Fragments
A new performance budgeting system knows when to let particles and fragments stick around, and when to get rid of them to keep everything running smoothly and accurately.
Particles and fragments are now much more varied in appearance, from hot to cold, rocky to gaseous. They can also now be individually- or group-selected, to easily watch, move, or delete them, or even convert them into bodies.
4. Explosions Look More Epic & Cause “Shockwaves”
Combined with the improvements made to the particle & fragment system, explosions look a whole lot better in Alpha 19.
Also, explosions now simulate an expanding bubble of exploded material, which can collide with other planets, heating and ripping them apart.
Home → Open → Explosions tab
5. You Can Record Animated GIFs
Easily & instantly create animated GIFs like the ones above of planetary movement & destruction.
Press F9 to Start/Stop Video Capture
Or click the Video button in the bottom right for Start/Stop Video Capture and Video Capture Settings. These settings can also be found through Home → Settings → Video.
6. “New” Labels, Stats, & Sorting Options for Sims
All sims new to Alpha 19 have a “New” label which is replaced with a check mark once the sim has been opened.
You can hover over the sim tile to see sim stats, like when you last opened it, and you can now sort the sim list using the options next to the search bar.
7. New Object Models
We’ve improved the models for the Saturn V 3rd Stage rocket and New Horizons probe, and added The Great Pyramid of Giza and a new police box object.
Home → Open → Human Scale tab → Human Sized Objects
Add → Objects tab
8. New Music
Two new, original tracks by our composer, Macoubre.
9. And Hundreds More Improvements & Bug Fixes
With nearly an 8-page list of new features, improvements, and fixes, this is our biggest update by far. We’re very excited with all of the changes and would love to hear what everyone thinks!
Check out the full list of new features, improvements, & bug fixes in What’s New.

Updated 2016 Roadmap
Jun 20th
We’re now halfway through 2016, and that means it’s time for an update on the 2016 roadmap we shared at the beginning of the year.
What’s Completed?
1. Virtual Reality
This was a big one for us. Our recent blog post gathered some of the really amazing feedback we’ve been receiving about Universe Sandbox ² in VR.
We’re very proud of the results, and look forward to continually improving the VR experience. Check out the trailer below.
2. Tidal Forces
The new tidal heating and Roche limit effects add another element of realism to Universe Sandbox ², and they also look really cool. In Alpha 19, bodies now heat up and can be torn apart by tidal forces if they approach other bodies closely enough.
3. New Object Models
You’ve probably heard of the Great Pyramid of Giza, but have you ever seen it floating through space? Below is a preview of some of the pyramid blocks which will be available, but of course we’re also adding in the whole pyramid.
We’ve also added improved models for the New Horizons probe and the third stage of the Saturn V rocket, as well as a new, shiny police box. See more.
4. Bug Fixes
Our new Quality Assurance team member, Steven, has been busy testing, tracking down bugs, and assuring that when those bugs are squashed, we’re not inadvertently breaking anything else.
With Steven’s help, and the help of our new developer, Jonathan, we’ve been able to fix a big list of long-standing issues. For a complete list of what’s been fixed, see our release notes.
What’s Next for 2016 and Beyond?
1. Alpha 19
We’re rounding the corner on Alpha 19, which should include the tidal forces, new models, and bug fixes mentioned above, as well as some beautiful new supernova visuals.
2. VR Update
Right now the VR version is separate from the desktop version, so Alpha 19 will only be a desktop update. But we’ve been looking at feedback on the VR version, and we plan to address some of these issues with a small VR update after we release Alpha 19.
This VR update should include:
- A new tutorial to better explain controls & mechanics
- Save and Load
- A bunch of bug fixes
3. Alpha 20
Alpha 20 is looking like it’ll be a very big and exciting update.
Here’s what we hope to include in Alpha 20:
- Automata (more planetary details)
- Increased spatial resolution for a planet’s data means that it’s possible to affect values locally
- For example, this should help with local temperatures, like impact and laser heating; terrain deformation; and, further down the line, life simulation
- Total body fragmentation
- Combined with the new tidal forces and explosion effects in Alpha 19, total body fragmentation should be a very impressive effect
- Merged VR and desktop versions
- After merging we’ll be able to release updates for VR and desktop simultaneously, and more easily integrate features for both versions
- Complete feature parity for the VR interface will take longer, but this is an important step in that direction
- Rewritten user interface
- Allows for scaling the interface for higher resolutions and…
- Language localization (coming later)
4. Alpha 21 & Beyond
After Alpha 20, we’ll be setting our sights on some even bigger projects:
- Stellar evolution
- The new model supports 16 star types, versus the previous 5
- The result should be more dynamic and accurate properties for stars, as well as smoother transitions between types
- If we’re lucky, we’ll have this ready for Alpha 20, but a safer bet is Alpha 21
- Life simulation
- There’s a lot of planning to do on this, but the Automata tech coming in Alpha 20 should help pave the way for the beginnings of life simulation
- Space megastructures
- These accidentally made it into an experimental build of Alpha 19, and if you had a chance to see them, you know that they’re very cool, but they still need a lot of work before they are more interactive and less CPU-hungry
- Mobile
- We just hired a dedicated mobile developer, Dave Nelson, who will be working full-steam on a mobile version of Universe Sandbox ²
- This is still in preliminary phases and we don’t have a timeline for release yet
- Steam Workshop support
- Being able to share saved simulations and objects will open up the creative potential even more
- Language localization
We’re very happy with the progress we’ve made so far in 2016. And we’re very excited for what’s in store for the rest of 2016. We hope you share our enthusiasm for exploring this crazy and ambitious project.
