Universe Sandbox 2 V34.1.1 May 2026

Release Summary: Update v34.1.1 is a stability and improvement patch following the major v34.0 "Supernova" release. The headline feature of this version cycle is the complete overhaul of how supernovas are simulated, alongside significant performance improvements for collision calculations.

Let’s walk through a specific experiment only possible reliably in Universe Sandbox 2 v34.1.1: Creating a habitable moon around a gas giant. Universe Sandbox 2 v34.1.1

Step 1: Load the "Jupiter & Io" preset. Step 2: Select Io. Open the Atmosphere tab (New UI in v34.1.1). Step 3: Click "Add Atmosphere." In v34.1.1, you can drag a slider for "Magnetic Field Interaction." Set Jupiter's magnetosphere to "Protective." This prevents the gas giant's radiation from stripping the new atmosphere. Step 4: Use the Heat Map tool (F3). The new overlay shows temperature distribution. Adjust the distance slider until the average temperature hits 280 Kelvin. Step 5: Watch the Ocean Shader. In previous versions, oceans looked static. In v34.1.1, tidal forces from Jupiter will visibly bulge the water on Io’s surface. Release Summary: Update v34

The fact that you can do this in real-time, with accurate gravitational mathematics, is why this version is revolutionary. Step 1: Load the "Jupiter & Io" preset
