Run Steam to download Update 25, or buy Universe Sandbox via our website<\/a> or the Steam Store<\/a>.<\/p>\n Update 25 brings significant improvements to our temperature and surface simulation, adding stability and accuracy, drastically improving speed, new object properties, and a rewrite to our tidal heating model. We\u2019ve also added some often-requested features such as \u201cReplace Object\u201d and graph data export, as well as relocating save data associated with removing the \u201c\u00b2\u201d from \u201cUniverse Sandbox\u201d.<\/span><\/p>\n Major Surface Simulation Performance Improvements Temperature & Atmosphere Rewrite Hot-swappable Celestial Object The \u201c\u00b2\u201d is Silent <\/p>\n Check out the full list of What’s New in Update 25<\/a><\/p>\n <\/p>\n
\n<\/b>Moving from Shader Model 3 to 5, a feature of most modern graphics cards, allowed us to utilize new technology (compute shaders), lowering the video memory requirements of the surface simulation by almost half and increasing performance substantially. Moving forward, this will allow us to add additional complexity to surface grids, better collisions (using smoothed-particle hydrodynamics), and gorgeous graphical features. Because of this change, we have updated our minimum system requirements.<\/span><\/p>\n
\n<\/b>Tidal heating and temperature calculations have just received a major rewrite. This includes significant improvements to vapor flow, atmosphere energy retention, and overall object energy absorption and radiation. You can see these properties in action in the new Energy Flow section in an object\u2019s Surface tab, and in our new Energy and Heating guides.<\/span><\/p>\n
\n<\/b>A “Replace Object” button has been added to the Properties panel. This will allow you to hot-swap any object in the simulation for any other object, enabling a bunch of fun scenarios that were hard to do in the past.<\/span><\/p>\n
\n<\/b>Just call us \u201cUniverse Sandbox\u201d, we\u2019ve gotten rid of the \u201c\u00b2\u201d. When loading the update for the first time, you may notice a “Migrating Data” message. We’re automatically reorganizing settings and saved files to reflect the name change.<\/span><\/p>\n![\"\"](\"https:\/\/universesandbox.com\/blog\/wp-content\/uploads\/2020\/03\/Universe-Sandbox-20200313-160426-1-screenshot-650x392.png\")
