Universe Sandbox 2 - How to Use Surface Grids & Lasers

This guide is a pretty simple guide. It’s self-explanatory, this guide will teach you every basic step about surface grids and lasers!

What is SG&L?

Surface Grids and Lasers (SG&L) is a feature that allows for plenty of more accurate data on a planet! (Lasers are a fun tool). In this guide, I will be teaching you how to use these features!


This one is very important! Before you get started, we have to talk about this. Universe Sandbox 2 used to run very good on low-end computers before SG&L. But now it runs poorly. So let’s talk about optimization!

You may do a performance test to check your results. I got 275 FPS with an RX-590, so SG&L is still pretty optimized. However, that may not be the case with your PC. Go to Settings > Performance. Chance your Atlas Resolution if you think it is too high, as it causes a dramatic performance impact at the high resolutions. Then, go to “Target FPS” and set it to however you want. (Recommended to be the same as your monitor refresh rate). Head back over to Settings, and then go to the ‘Graphics’ tab. Check your graphics and make sure they aren’t too high!

The Basics

Now that we are done with that, let’s move onto the fun part! Before the update, planets looked bland and boring. Now they have a huge graphics improvement, with more varieties aswell! Let’s add a planet! The planet may or may not be icy. If it’s icy, remove some water. Looks a bit better!

Now, go to tools in the bottom middle of the screen, then Laser. Increase your power to around 10 ZW and 1000 KM radius. Now hold down left click on a targeted planet! Fun, right?

Advanced SG&L

Now you’ve learned the basics! Let’s try something new. Start a new simulation, and place a planet. It might look a bit barren, so let’s fix that! Click on the planet, click on the tab that pops up, and go to the “Surface” tab. Then, scroll to the bottom and set the atmospheric pressure to 99 kPa (99,000 Pa).

After that, scroll up and change the average surface temperature to 15 degrees Celsius (59 degrees Fahrenheit). Congrats, the planet is slightly habitable! Now, head over to Tools < Materials. A menu should pop up. Change it to something around these settings. (I recommend slowing the time-rate to 5 minutes a second.)

After, aim for the newly created planet and spray water all over it! You may notice that there is not enough water coming out, so change the Particle Mass to 0.001 Ocean. After, try again!

The planet will be filled with water! Spread it throughout the planet, then head over to the materials tab. Add a tad bit of hydrogen, then speed up time. Clouds will form!
