Description
WorldEdit Selection Overlay (Fabric)
Make your WorldEdit selections visible, readable, and predictable.
What is this?
WorldEdit Selection Overlay is a client-side visual addon that shows your selection exactly as it is before you run any destructive commands.
No more guessing shapes.
No more wrong sizes.
No more accidental //set air.
You see everything in advance.
Why you actually need this
WorldEdit gives you power, but almost no visual feedback.
This mod fixes that:
- See the real shape of your selection
- Read dimensions directly in-game
- Inspect blocks before editing
- Isolate specific block types inside a selection
- Avoid mistakes that cost time
In-Game Preview
The overlay renders your selection directly in the world:
- Exact bounds
- Real geometry
- Clear corner points
Built-in Dimension Ruler
Measure selections like in CAD tools:
- Clean readable size labels
- Always visible from your current angle
- Can follow your camera or stay fixed
Overlay Palette Editor
Customize how the overlay looks directly in-game:
- Full-screen color editor with live selection preview
- Per-element color, transparency, and line thickness
- Ready-made presets for different visibility needs
- Reset controls for one element, thickness, colors, or everything
Inspect Before You Edit
Open the block viewer and see exactly what is inside:
- All blocks in the selection, including
air - Grouped and searchable
- Fast filtering with
#air,#fluid, and#solid - Chunk-aware loaded/unloaded counts
- Fluid entries use bucket icons for easier reading
Perfect before using:
//replace//set//stack
Block Isolation Mode
Need to find only one material inside a huge selection?
Select one or more block types in the block viewer. The mod hides every other block inside the selected WorldEdit region on the client only, leaving the real world untouched.
Useful for:
- Finding hidden ores, liquids, air pockets, containers, or mistakes
- Checking what a
//replacecommand will affect - Inspecting complex builds layer by layer
- Viewing selected blocks with their normal textures
Details:
- Multiple block types can be selected at the same time
- Selected block groups stay pinned above the rest of the list
- A reset button clears the isolation selection quickly
- Fluids and fluid-like rendered content are hidden when they are not selected
- Selected blocks and fluids are rendered full-bright so their textures stay readable
- The selection boundary and ruler can stay visible while the internal grid is hidden
- Works even when the normal selection overlay visibility is disabled
Everything is visual only. Hidden blocks still exist, still collide, and are never changed by the mod.
Features
- Real-time selection overlay
- Two render styles: Blocky / Smooth
- Optional internal selection grid toggle
- Full-screen palette editor with live preview
- Custom colors, transparency, thickness, and presets
- Adaptive performance for large selections
- Optional diagonals for cuboid shapes
- Built-in dimension ruler
- Block inspection screen
- Client-side block isolation mode
- Fluid-aware rendering and bucket icons
- Full-bright isolated blocks and fluids for readable textures
- Fully configurable UI
Supported Selection Types
- Cuboid
- Polygon 2D
- Ellipsoid / Sphere
- Cylinder
- Polyhedron / Convex
Works with everything WorldEdit sends via CUI.
