Brown Dwarf Transitions

We’ve made significant improvements to the simulated transitions of gas giants into brown dwarfs and stars, driven by a newly simulated Fusion Power energy property. Learn more about fusion power and brown dwarfs in our new guide: Guides > Science > Are Gas Giants Failed Stars? 

More Color Customization

The color of water on all planets, and the color of vegetation on Earth, are now customizable via Properties > Appearance.

Laser Improvements

Laser presets have been reorganized, and we’ve added a new Push Water setting in the Laser panel. While not entirely realistic, this is a fun way to play with the water simulation on an object’s surface. Try out the “Wave Maker” laser preset to create massive waves in a planet’s oceans..

Please report any issues on our Steam forum, on Discord, or in-game via Home > Send Feedback.
