RGBCraft 0.2.0-beta.1

A major update focused on smart-home automation, large RGB displays, new fixtures, and high-performance colored lighting.

Highlights

• Added performant, shader-free colored lighting with adjustable quality, intensity, range, and render distance.

• Added Smart Home and Wireless Smart Home controllers with zones, groups, scenes, patterns, and remote fixture assignment.

• Added a Screen Controller supporting displays up to 16,384 pixels.

• Added Creative Controllers for unrestricted large-scale builds.

• Added RGB glass, light pillars, string lights, diffused strips, LED profiles, panels, corners, junctions, and crossings.

Colored lighting

• Added a fixed-cost, camera-local colored-light volume.

• Added Low, Balanced, and High quality presets.

• Added configurable intensity, reach, and render distance.

• Colored lighting works without Veil; Veil remains an optional legacy backend where supported.

• Added compatibility adapters for several popular Iris shader packs.

• Fixed white flashing, flickering, incorrect camera projection, and checkerboard rendering artifacts on Forge 1.20.1.

• Unsupported hardware or shader configurations safely fall back to emissive rendering.

Smart-home system

• Added named lighting zones with individual power, colors, brightness, effects, BPM, speed, width, easing, and transitions.

• Added priority groups with per-field inheritance and overrides.

• Added whole-home scenes that capture and smoothly restore every zone.

• Added a world-level pattern library with 11 built-in presets and editable custom patterns.

• Applying a pattern copies it into the zone, so later pattern edits do not unexpectedly change existing setups.

• Added drag-and-drop zone ordering.

• Added zone duplication, renaming, deletion, and fixture identification.

• Mapping wands can highlight fixtures belonging to their bound zone.

Controller and effects UI

• Rebuilt the controller interface with a larger, less cramped layout.

• Added separate editors for zones, groups, fixtures, patterns, and scenes.

• Added live zone color swatches and quick power controls.

• Added secondary color, effect speed, width, easing, and transition controls.

• Made the Step easing mode accessible.

• Unassigned fixture lists now display the translated fixture name alongside coordinates, pixel count, and ownership.

• New controllers start powered off.

Screen Controller

• Added automatic mapping of connected coplanar fixture surfaces.
• Supports holes, rotation, flipping, palettes, calibration patterns, and raw drawing operations.
• Added a CC:Tweaked monitor-style drawing API.

Fixtures and building

• Added RGB glass and four-pixel light pillars.

• Added four-pixel string lights with proper names, corners, and branching connections.

• Added iron, copper, deepslate-brick, and quartz LED profiles.

• Added standard and diffused surface fixtures.

• Surface lighting can form straight runs, bends, wall transitions, inside/outside corners, T-junctions, and crossings.

• Added the RGB Surface Wrench for controlling connections and removing individual face segments.

Fixes

• Fixed the Zones tab disappearing while controller data was synchronizing.
• Fixed controller resizing duplicating effect buttons and eventually crashing.
• Fixed smart-home group resolution leaking state between unrelated zones.
• Fixed several controller-opening crashes and GUI visibility problems.
• Preserved existing controller power states and registry IDs for world compatibility.
