In 2011, Dan hired two developers to begin work from the ground up on a new Universe Sandbox.  By 2012, the team had added two developers, and the demo they showed that summer in Amsterdam at the Unite conference was impressive and promising.

A few weeks ago, PAX Prime finally let us deliver on that promise.  We’re now a team of seven developers, and we’ve been working on Universe Sandbox ² for almost three years… There is nothing more thrilling than seeing eyes light up and jaws drop at the sight of a molten Moon inching its way toward an unsuspecting Earth. Yes, jaws dropped.

“And it’s all simulated in realtime using real physics,” we’d mention, though few peeled their eyes away from our planet’s destruction. Understandable; it does look pretty cool.

But those who stopped by our booth weren’t just impressed with the cosmic eye candy. We had plenty of astronomy and physics buffs swing by who were eager to discuss the data and mechanics behind it all. Of course, that’s what gets us excited, too.

In short, PAX was exhausting, exciting, and above all inspiring. Having a space in the Indie MEGABOOTH reminded us all that we’re part of an incredibly supportive and energizing community.

While not all of us were able to attend, we hope to get the whole team together again soon so everyone can experience firsthand our fans’ reactions. It truly is great seeing others express as much enthusiasm as we do for our unique simulator.

Fortunately, there’s plenty of time for showing off in the future. We are still in alpha. There’s a lot of work to do.  Demoing for four days also revealed some issues, but it also made us all the more excited to continue fixing and improving. We look forward to making Universe Sandbox ² the best it can be.

Access Older Versions of Universe Sandbox

If you have older hardware that is unable to use the latest version of Universe Sandbox, you can try to run older versions of Universe Sandbox that have lower requirements.

If the following version doesn’t work, you can try an even older version.

Steam Version

1. Exit Universe Sandbox
2. Right-click on the game title in your Steam Library
3. Click on Properties
4. Select the Betas tab
5. Set the dropdown menu to *update-24.1.2-directx10
6. Close the Properties window
7. Steam will now update Universe Sandbox to the last DirectX 10-compatible build
8. Once updated, launch Universe Sandbox

GOG Version

1. Open the game card for Universe Sandbox in GOG Galaxy Library.
2. Select the More option then Settings.
3. Select ON from the drop-down menu in the Beta Channels option on the right-hand side.
4. A Channel option should now be visible. Select the channel update-24.1.2-directx10
5. Click INSTALL

Why?

In order to continue improving Universe Sandbox, we need to take advantage of ever-improving graphics technology. Unfortunately, this means that sometimes we must drop support for older hardware that can’t handle these new requirements.

Still won’t run?

If you’re still unable to run Universe Sandbox, please contact us for support or to request a refund.

1. Opening the simulation in Universe Sandbox
2. Selecting the Home icon in the top-left
3. Selecting “Save & Share”
4. Adjusting the name or description of your simulation as desired, then select “Save”

For objects, you can do this by

1. Selecting the Home icon in the top-left
2. Select “New” to open a new simulation
3. Selecting Tools > Add
4. Selecting the “My Objects” tab
5. Adding the desired object to the simulation

Steam Required

You may see an error message when starting up that says “Steam Required: You must be running Steam to use Universe Sandbox.”

This is a Steam error which sometimes appears even if Steam is running. It is a frustrating error, but it is usually fixed once Steam properly syncs again.

Update 24 Minimum Graphics Requirements

As of Update 24 in November 2019, Universe Sandbox includes a feature called Surface Grids which vastly improves the surface simulation of planets, moons, and other objects. This feature relies on video memory. Some computers with low amounts of video memory or shared video memory may struggle with running Surface Grids.

If Universe Sandbox consistently runs slowly, try lowering Surface Simulation | All Maps Atlas Resolution in Home > Settings > Performance.

If it continues to run slowly after lowering Surface Simulation | All Maps Atlas Resolution, we recommend using the previous version of Universe Sandbox, Update 23.2. Learn how to switch to Update 23.2

Can’t Access Documents

With macOS Catalina (10.15), security measures in macOS have been greatly increased and users must specifically give permission to applications to access their files. When you start Universe Sandbox for the first time in macOS Catalina, you should see a prompt asking if you want to allow Universe Sandbox to access your Documents folder. Click OK.

If you do not click OK or you do not see this prompt, you will see an error message in Universe Sandbox when attempting to access your saved simulations and objects. To fix this, adjust your Security & Privacy settings:

1. Click the Apple icon in the menu bar
2. Click System Preferences
3. Click Security & Privacy
4. Click the Privacy tab
5. Click Files and Folders
6. Check the box below Universe Sandbox (if required, click the lock icon in the bottom left and enter your password to make changes)

If the issue persists, please reinstall Universe Sandbox and follow the steps above again.

Your Settings/Data Need to be Moved Manually

Why?

Universe Sandbox removed the 2 from our name as of Update 25 in March 2020. Due to limitations of our game engine our data folders will need to be renamed along with the change to the app name.

Universe Sandbox will attempt to relocate these files automatically. Some system settings or security software such as antivirus or firewall may prevent Universe Sandbox from automatically relocating these files.

How to move your files:

1. From within Universe Sandbox, click Home
2. Click the “Action needed to move your Universe Sandbox settings/data.” banner
   
3. Click on “OPEN FOLDERS”.
   
   Two folders will open outside of Universe Sandbox: “Universe Sandbox ²” and “Universe Sandbox”.
4. Click and drag to highlight all files in the “Universe Sandbox ²” folder (note the 2)
5. Drag and drop the files into the “Universe Sandbox” folder

This is an LFAQ (less frequently asked questions). Here is an FAQ for Universe Sandbox ².

 

Will there be a mobile version?

Maybe. It is possible, but we wouldn’t begin development until after the initial release for PC, Mac, and Linux.

 

Will there be a free version?

We’re discussing the possibility of a feature-limited version, but not until after the initial release.

 

How much will it cost?

Pricing has not yet been decided. It will, however, cost more than the current price for the original Universe Sandbox ($9.95 USD). Educational discounts have not yet been determined either.

 

Will it support other languages beyond English?

After the initial release, we plan to incorporate support for additional languages.

 

Will there be sound effects and/or music?

Yes, we are working with a composer who will be creating an original score. There will also be sound effects. If you’d rather experience the silent desolation of space, though, there will be an option to turn these off.

 

Will you be able to simulate evolution/life on planets?

We plan to incorporate very basic support for “life.” Essentially, given the right conditions — temperature, atmosphere, water, etc. — vegetation will grow on planets. Greater complexity may be developed in the future, but it’s a long way off.

 

Will there be support for Steam Workshop?

We plan to add support for Steam Workshop that will, in the least, allow for sharing user-created simulations.

 

How about modding?

Making it easy for the community to create mods is a great idea.  “Light” modding will hopefully be available by release, with more extensive modding possibilities made possible later on.

Universe Sandbox ² developers Chad and Georg recently hosted a live stream demo of Alpha 8.

They answered questions from the live stream chat and showed off various improvements and features in the upcoming alpha, including the latest iterations of collisions, climate simulation, and material composition.

As the dedicated physics programmer, Thomas has lately been hard at work revamping and refining collisions in Universe Sandbox ².

Our Alpha testers have just begun to dig into Alpha 7, which shows off a completely reworked collision system.  But the work of a physics programmer is never complete, so subscribe to Thomas’s YouTube channel to stay updated on his progress in simulating the universe.

 

Watch Chad run through some of the new features and updates in the upcoming Alpha 7:

Included: terraforming Mars and turning it into a star, tidally locking the Earth, and the ever-popular but now better looking Moon & Earth collision.
