Space Station Designer Version 00.06.50 Updates Visuals and Free Builder Modes
Space Station Designer version 00.06.50 adds Free Builder to Sandbox conversion, nearly 250 new astronaut portraits, and official mod updates.
Polar Motion releases version 00.06.50 for Space Station Designer, bringing new visual assets, expanded Free Builder functionality, and interface layout adjustments.
Free Builder to Sandbox Conversion
Free Builder sessions can now be converted into Sandbox sessions via a button in the top left corner. The game automatically assigns astronauts to cover maintenance needs and enables contracts, module purchases, and astronaut management.
Visual Overhauls and Audio
All existing astronaut portraits have been replaced with a set of nearly 250 new images. Space station modules and resupply spacecraft materials have also received quality upgrades. Additionally, 2D animations for spacecraft launch sequences were revised, and new sound effects were added to the Earth Facilities and Module Repair screens.
Interface Layout and Achievement Code
The main space station screen layout was tweaked, placing the remove modules button closer to the module slots at the bottom of the screen. Code support for 50 unique Steam Achievements has been added, with a handful currently enabled and more scheduled for upcoming backend updates.
Modding and Official Documentation
Incompatibility issues with official mods have been resolved. All official mods have received updated versions alongside revised official documentation.
Why this patch matters
Version 00.06.50 streamlines station management with UI ergonomics, mode conversions, and visual refreshes across astronauts and modules.
