# Rivencraft 26.3 beta 1.0.1.71-beta.1

This beta collects the player-tested lighting and sky port slices since
1.0.1.65-beta.1. It is not yet feature-complete with Minecraft 1.21.1.

## Lighting and seeded environments

- Added Normal, Dark, and Bright lighting pages with saved per-Age settings.
- Bright works in Cave terrain too, without adding skylight or weather.
- Bright supplies effective ambient light level 15 to native combined-light
  checks and the white ambient rendering attribute. Vanilla darkness-based
  monster checks respond to that lighting; there is no separate mob-spawn
  veto. Mobs that ignore light retain their normal rules.
- Missing weather and lighting controllers now resolve deterministically from
  the Age seed, using independent choices and Legacy-style Normal weighting.
  Explicit pages win; Cave terrain still forces weather Off. Existing Ages
  keep their saved choices rather than rerolling on load.

## Sky styles

- Added Overworld, Nether, End, and animated Static Sky pages, independently
  of terrain, weather, and lighting. Choices persist on reload and restart.
- Nether Sky uses a reddish fog backdrop; End Sky uses the native End sky.
  These are visual styles, not Nether/End terrain or gameplay conversions:
  dimension geometry, coordinate scale, bed/water rules, and dragon behavior
  are not changed.
- Static Sky adapts the existing Legacy-style renderer: six independent
  48×48 animated gray noise faces. A cached cube and small dynamic texture
  avoid rebuilding thousands of per-cell vertices each frame. Client-only
  rendering resources are released with the sky renderer.
- Non-Overworld backgrounds have transparent clouds and a derived day
  timeline that avoids Overworld sky/fog/cloud color tracks while retaining
  gameplay and illumination schedules.
- Updated supported-page feedback and added operator sky/environment probes.

## Current limits and testing

- Missing Sky pages still default to Overworld; random sky selection, color
  pages and individual celestial bodies remain pending. Number-controlled
  Static Sky resolution is tracked separately in issue #109 for both versions.
- The writing/discovery loop, instability, portals, and optional-integration
  parity are still incomplete. Creative availability is not a support claim;
  check page tooltips and the beta guide for supported combinations.
- Previously generated chunks are not regenerated. Save compatibility during
  the beta is not guaranteed; keep backups and keep both version tracks apart.

The player reported in-game passes for the included slices, including Static
Sky. Build checks passed for both version tracks. Targeted disposable-server
checks covered environment defaults, explicit choices, registered sky/lighting
variants, persistence and restart, including Cave + Bright and Static Sky.
This is not a claim of complete dedicated-server or optional-mod coverage.
Test servers were stopped and temporary worlds removed.

Requires Minecraft **26.3**, NeoForge **26.3.0.99** and **Java 25**. Dynamic
Dimensions and Bad Packets are not required by this build. The 1.21.1 release
and its dependencies are unchanged.
