# RingWorld 1.4 ## Server performance - Spread automatic world saves over several ticks > Reduces the pause when a busy server saves > Tested autosave tick: ~387 ms → ~106 ms. - Reduced bursts of chunk cleanup and location checks while travelling > Less freezing when moving between loaded areas > Worst movement tick, excluding garbage-collection pauses: ~1,029 ms → ~177 ms in the paired test. - Reduced temporary memory use when updating lighting > Fewer long pauses while chunks load and unload > Memory allocation: ~254 MiB/s → ~181–183 MiB/s; worst server tick: ~796 ms → ~266–277 ms across two follow-up tests. The earlier 682 ms full garbage-collection pause did not recur. - Moved regular Atlas file writing into the background > Saving the distant terrain map no longer does its compression and disk writing on the gameplay thread; progress is preserved for resuming later. - Removed repeated checks of the entire completed Atlas > Reduces recurring server work when players view generation progress, especially on Large rings. ## Generation and Atlas updates - Added automatic chunk-generation speed control > Pregeneration can run faster when there is spare capacity and slow down when performance drops > Auto starts at four requests; `/ringworld chunk_gen_rate 1|2|4|8|auto` changes it live. - Made Atlas updates from newly loaded chunks adapt to server load > Reduces bursts of work as players explore; the distant view can catch up gradually during heavy loading. ## Building - Enabled building beyond the side walls > Build platforms and structures outside the ring > On by default, with a World-menu toggle and `/ringworld building outside on|off|show`. On servers, operators control the setting for everyone; turning it off keeps existing builds. - Fixed players and nearby entities disappearing outside the walls > Characters and other nearby entities remain visible when stepping off the ring. ## Rendering - Closed gaps along the distant terrain edges and damaged wall sections > Fewer visible holes between the terrain and walls. - Matched distant walls to the configured wall height and depth > The distant wall stays aligned with the real wall, including its top edge. - Improved the changeover between real blocks and distant terrain at altitude > Looking down from high above the ring no longer leaves the same terrain gaps. - Made clouds follow the configured wall height > Clouds look more consistent when viewed from different heights and on rings with different wall sizes. - Removed the flat Overworld horizon band > Cleaner skies around the ring, including sunrise and sunset. - Added nearby block correction > Reduces squeezed and stretched blocks on small rings > On by default; toggle it in Display settings or with `/ringworld distortion on|off`. `/ringworld distortion distance <1–8>` adjusts its range. This changes appearance only. - Improved how the Atlas handles floating platforms > Recognized thin, manufactured platforms with clear air underneath no longer turn the terrain below into artificial mountains in the distant view. Natural terrain and unrecognized materials are kept. - Corrected distant wall settings on Minecraft 26.3 > Wall style, height, decay and seed now match the saved world settings consistently across supported versions. ## Mod compatibility - Reworked the shared rendering core > Improves compatibility with rendering mods while preserving the existing ring appearance. - Improved shader compatibility by preserving Minecraft's shader state > Other rendering mods have fewer shared-state conflicts. This does not establish general Iris or shader-pack support. - Added experimental Sodium support and fixed its terrain curve and Atlas transition > Real blocks, walls and water line up with the distant ring. Sodium compatibility remains experimental; see the compatibility notes. - Hide the distant Atlas underwater > Nearby blocks keep normal water fog, without the far ring showing through; resurfacing restores the ring, including after a resource reload. ## Download size and cleanup - Compressed the wall preview images > Smaller downloads while keeping the previews in the selector > Development JARs: ~13 MB → ~3.3 MB, about 75% smaller. - Tidied shared seed-preview code > Reduces duplication between supported versions. ## Versions and testing Applies to Minecraft 26.1–26.1.2, 26.2 and 26.3 on Fabric and NeoForge. Older Atlas caches rebuild automatically for the floating-platform change. Performance figures come from development tests on a pregenerated Large ring with three players and a 4 GiB server heap. Autosave/movement and lighting figures come from separate stages of that testing; they are not chunk-loading times or guaranteed results on every server. Shorter pauses still occur.
