Enlighten 1.0.2a — Release Notes

Minecraft 1.21.1 · NeoForge 21.1.x · Java 21

Enlighten 1.0.2a adds the Fluid Fill tool and finishes a large editor UI/input polish pass.

New: Fluid Fill tool

• Added a sixth editor tool, Fluid, for filling enclosed areas horizontally.
• Right-click a point inside a wall to fill from the adjacent air cell at that surface.
• Two modes:
  • Layer — fills only the clicked height.
  • Below — fills each reached column down to the first solid block.
• Flood fill moves through air and existing fluids. Solid walls and floors are never replaced.
• Existing fluids can be replaced with the selected fluid.
• The fluid picker lists source fluids only, including modded fluids, and uses the correct bucket icon.
• The editor mask is evaluated against the clicked block, not the air in front of it.
• Maximum fill extent is 256 × 256 × 256 by default and can be changed in M → Other → Fluid fill size.
• Oversized fills are cancelled before any block is changed and report an on-screen warning.

Block pickers

• Surface, noise replacement, mask, fluid, and RGB block pickers now use full-row paging.
• No half-clipped textures or empty rows while paging.
• Fluid pickers show the actual fluid icon instead of always showing a water bucket.

Editor UI

• Tool palette is now a two-row, three-column layout with properly centred English labels.
• Left and right panels use the same width for a balanced layout.
• Fluid mode uses separate Layer / Below buttons with a single contextual description.
• The fluid brush sphere was replaced with a target block outline.
• Preset dropdown is a compact floating list; it sits above panel content but below the crosshair.
• Block picker and RGB picker scrolling is stable and clipped correctly.
• Config page scrolling is smooth, content is clipped at the viewport, and clipped buttons can no longer be clicked.
• Warning and status messages fade in/out with a short alert sound.
• Notes and footer hints wrap inside the panel and no longer overlap.
• Crosshair is rendered above item icons and other editor textures, with symmetric pixel extents.

Input fixes

• Tool shortcuts are disabled while any screen or text field is open.
• Typing z / y / a in a preset name no longer triggers undo, redo, or clearing.

Compatibility

• Minecraft 1.21.1
• NeoForge 21.1.x
• Java 21

This release targets 1.21.1 only.
