# RingWorld 1.4 is out for Minecraft 1.21.1 You can now play RingWorld on **Minecraft 1.21.1**, with releases for **Fabric and NeoForge**. This backport brings the core features of the 26.x release to 1.21.1: the Ring Atlas, adaptive terrain generation, background saves, weather fading, and smoother transitions between nearby blocks and distant terrain. It also includes improvements to mesh uploads and Atlas cache handling for this version. All of this functionality is backported from 26.x, so the experience on 1.21.1 may not match 26.x exactly. **Requires Java 21.** Fabric also requires Fabric API. For multiplayer, install the same RingWorld version on the server and all clients. RingWorld is still a work in progress. If something breaks or looks wrong, please [report it on GitHub](https://github.com/Delaser/RingWorld/issues).

# 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.

## RingWorld 1.3 — Minecraft 26.3 (NeoForge) ### World creation and controls - Rebuilt the RingWorld world-creation editor with separate Ring, Terrain, Walls, Sky, and Preview pages. The selected wall style now appears alongside its controls. - Added **Use** to the seed preview. Previewing or rerolling a seed leaves the world seed alone; **Use** locks in the previewed seed, and **Apply settings** copies it to Minecraft's World tab. That tab shows when the seed came from RingWorld. Cancelling the editor discards unapplied changes. - Reorganized the in-world panel so generation controls are separate from the player's Low, Medium, and High distant-ring detail setting. ### Gameplay and compatibility fixes - Fixed the black block-selection outline and mining cracks sliding sideways from the targeted block above or below the ring surface. - NeoForge files now accept loader builds newer than the stated minimum instead of rejecting them because they exceed the loader version used during testing. Minecraft version requirements are unchanged. ### Distant ring and transitions - Fixed distant terrain polygons flashing as the camera moves, most visible on sharp ridges and high-contrast structures. The distant wall pattern now uses filtered textures to reduce shimmer during movement. - Replaced irregular fade speckle with a fixed ordered pattern where real blocks give way to the distant ring. - Made distant wall colours follow the active block textures more closely, including resource packs. - Reduced the pale fog line where loaded land meets the distant ring. Water now fades toward the distant colour more gradually. The Atlas records actual water coverage rather than guessing from blue colour and sea level, so rivers and water above sea level receive the same treatment. ### Stability and performance - Reused unchanged distant-wall textures during Atlas updates, reducing repeated GPU uploads. - Delayed complete Atlas cache snapshots until incoming tile updates settle, reducing repeated cache-copy work during updates. On 26.3, resource reload no longer crashes when the new sky renderer has not recreated its colour state. Shader compilation also has its own worker so a busy chunk generator cannot hold up startup or reload. Those two failure mechanisms do not exist in the 26.1/26.2 renderer APIs. The transition between real chunks and the distant ring can still reveal heightfield differences around cliffs, trees, and thin structures. Some Atlas uploads and cache copies can still cause occasional long frames. Atlas caches rebuild after updating to 1.3, so the distant ring may take time to reappear. Update the server and its clients together. Corresponding source: [exact commit](https://github.com/Delaser/RingWorld/commit/f1b243af48f44452179f7a109877799584c8f47d).
