Universe Sandbox Update 34.1 (specifically version 34.1.1) focuses on refined planetary simulation and visual improvements following the major "Terraforming" Update 34. Key Features of Update 34.1
🪐 Universe Sandbox 2 – Version 34.1.1 Release Post
Build ID: 34.1.1
Release Date: April 2026 (current stable)
Platforms: Windows / macOS / Linux / SteamVR Universe Sandbox 2 v34.1.1
now contribute to a planet's color and opacity, rather than just the four most massive ones. For example, adding sulfur dioxide will now visibly tint an atmosphere orange. Material Swapping Universe Sandbox Update 34
- v34 improved support for adding custom models and textures, making it easier to share custom objects (like sci-fi ships or custom planets) via the Steam Workshop.
Key Features
1. Full Atmospheric Simulation (3D Fluid Dynamics)
- Pressure & Temperature Modeling – Each planet now maintains a dynamic atmospheric grid (resolution adjustable). Gases flow, heat, compress, and escape based on solar wind and planetary gravity.
- Gas Composition Editor – Mix oxygen, CO₂, methane, sulfur dioxide, and 12 other gases. Watch plant life (if seeded) convert CO₂ to O₂ in real-time.
- Weather Effects – Storms, hurricanes, and dust devils form visually and affect surface temperature. Wind strength depends on rotation speed and axial tilt.
- Atmospheric Drag – Satellites and asteroids now slow down and burn up upon entry (with reentry glow).
