Create Cosmonautics

Version 26.08.307 (Beta / Pre-release)

This is a pre-release containing major performance improvements, security enhancements, and community contributions.

Performance Fixes:

• Star Frustum Culling: Optimized space stars rendering to prevent camera rotation lag.
• Double Rendering Fix: Resolved an issue where space stars were rendered twice at night.
• Planet Beneath View: The Earth/ground view above 1000m now bypasses config checks.

Config Changes:

• Custom Sky default state: The custom sky option (enableCustomSky) is now disabled by default.

Security Fixes:

• Restricted /rn limit_world_border to operators (permission level 2+).
• Restricted /sable to operators (permission level 2+).

Merged Pull Requests:

• PR #97: Sputnik Flight Computer multiplayer UI state preservation.
• PR #101: Simplified Chinese (zh_cn.json) localization updates.

• feat: add config options to disable custom sky rendering and toggle flame merging

Added:

• Sputnik audio synthesizer engine and Lua script wrapper
• Client-side custom synthesizer and playback payload
• Overworld custom sun and moon coordinate/distance fixes to prevent culling
• Vanilla-accurate ZP sky rotation and day time alignment
• World size limit warning prompt shown on first world join
• Clickable Da/Net chat components to run world border lock packet (limits to 40,000 blocks)
• Creative Rocket Thruster that operates solely on Redstone signals
• Mapped creative thruster to a unique purple/magenta exhaust plume color
• Space helmet item tooltip localized translations in English, Russian, and Chinese
• Custom main menu splash screen texts
• Corrected creative thruster block model texture namespace and render layer (cutout_mipped)

Changelog:

• Fixed an issue where satellite values were reset upon re-entering.
• Fixed a bug with node copying and incorrect node connections.
• Added new engine effects (open beta test - unstable).
• Added re-entry effect (currently triggered via /rn reentry command).

Changelog:

• Fixed Dedicated Server startup crash related to ClientLevel classloading.
• Removed camera shaking and block surface melting for RCS thrusters.
• Fixed a physics server crash (Body has been removed RuntimeException) that occurred when ships or sub-levels were destroyed/removed at supersonic speeds.
• Fixed an issue in the node editor screen where search filtering did not update correctly when reopening the search panel.
• Fixed an issue where double-clicking a newly created Lua Script node failed to open the script editor screen.

• Hotfix: Fixed planet rendering depth bug causing Earth to overlay ships.

• Added space helmet with improved GUI.
• Press Y to enable HUD with a target vector cursor in Deep Space.
• Added planet shape customization (spheres and cubes). Physics adapts to the chosen shape.
• Fully fixed the Sputnik and restored - Linked Redstone features.
• Fixed orbital mechanics calculations and planet rendering.

Features

• Added a new modular engine system built from three components, while keeping all the old engines intact.
• Added data-driven entity drag and atmosphere breathability.
• Added data-driven colors to generate planet textures directly from biomes.

Fixes

• Implemented several minor fixes.
• Fixed at least some of the issues people are experiencing with Deep Space.

Changes

• Changed Sputnik components to be powered by Lua instead of Java.
• Refactored a lot of under-the-hood code to support the new engine system.

Known Issues

• Note that old Sputniks will probably be broken due to the script language change.
• Anticipate potential new bugs with both the new and old engines due to the underlying refactoring.
