Use the new custom sim descriptions to detail the lore of your sci-fi worlds. Or discuss the reality behind the scientific phenomena in your simulations.

This update also includes changes to the interface with new tools for manipulating Property values plus styling improvements throughout. There’s a new autosave system to prevent accidental loss of work, and as always, there are lots of smaller improvements and bug fixes. See the full list of What's New

Notes:
1) Workshop only supports simulations at this time. In the future, we hope to add support for custom textures and models.
2) As of this update, Universe Sandbox no longer supports DirectX 9 or 32-bit operating systems. Users can run the last compatible version by selecting “*directx9-32bit” via Steam Betas (learn how). For more information on our decision to end support for DirectX 9 & 32-bit systems, please see our announcement from earlier this year.
