v0.1.3: Magic Select, Better Previews, and Faster Building Flow

Axion v0.1.3 is a quality-of-life release focused on making the tools feel faster, clearer, and easier to stay in. Selection previews are cleaner, stack and smear are more flexible, symmetry is more practical to build with, and Magic Select now has its own template system for custom masked selections.

Highlights

• Added Magic Select Templates with editable masks, custom mask creation, block picker search, and brush-size control
• Improved clone, move, stack, smear, erase, and symmetry workflows to reduce tool friction while building
• Added stronger scrolling previews with guide arrows, better ghost previews, and clearer helper text
• Expanded the Alt hotbar menu with more practical toggles for how edits should behave
• Added Mod Menu integration plus an in-game Axion config screen

Magic Select

Magic Select is the biggest addition in v0.1.3.

• Toggle Middle Mouse between Extend Face and Magic Select in the Alt hotbar menu
• Use MMB to select blob-style regions before setting a second point
• Use Main Mod + MMB to open Magic Select Templates
• Use Main Mod + Scroll to change the Magic Select brush size in-game
• Build selections from templates and masks instead of being locked to a single hardcoded behavior

Templates now support:

• Built-in defaults like Stone Types and Dirt Types
• Shared custom masks that can be reused across multiple templates
• Searchable block picking
• Native tag-style groups like slabs, stairs, wood, logs, and leaves
• Template and mask naming for easier recognition while building

Better Tool Flow

Several tools now stay out of your way more reliably:

• Clone confirmation keeps the preview active so repeated cloning is faster
• Stack and smear can continue in multiple directions before you confirm
• Move and clone flipping now respects camera direction
• Symmetry toggles can be changed while building if symmetry is your selected Axion subtool
• Main Mod + R / Main Mod + F now reduce conflicts with normal gameplay keys

Preview and UI Improvements

Previewing and tool readability received a large cleanup pass.

• Scroll previews now have direction arrows and more block-like transparent ghost previews
• Source-region pulsing and selection visuals are clearer and more consistent
• First and second cuboid points are easier to distinguish
• The in-game helper panel has better spacing and more useful Magic Select information
• Mod Menu now links directly to the project website and issue tracker
• Axion has a dedicated config screen, with Right Shift as the default keybind to open it

New Alt Hotbar Toggles

The Alt hotbar menu now includes:

• Middle Mouse
• Keep Existing
• Copy Entities
• Copy Air

These options let you control how tools behave without leaving the game.

• Keep Existing lets repeated tools avoid overwriting blocks you want to keep
• Copy Air controls whether air should replace existing destination blocks
• Copy Entities is intended for entity-aware move/clone workflows

Symmetry Improvements

Symmetry is much more usable in normal building now.

• Anchor nudging now works on .0 and .5 positions instead of only hopping between block centers
• Anchor placement uses the clicked location more naturally
• Rotational and mirror toggles now provide actionbar and toast feedback
• Symmetry visuals are easier to see and behave more consistently

Config Notes

New client-side configuration options are available through Mod Menu or by pressing Right Shift in-game.

• Main Mod: Ctrl / CMD
  • macOS-only helper toggle for using CMD instead of Ctrl
• Magic Select Templates
  • create, edit, enable, disable, and organize Magic Select behavior

Server / Paper Notes

If you use Axion on a server, update both the Fabric client mod and the Paper plugin together for this release.

v0.1.3 includes backend changes for newer tool behavior, especially around the newer copy/move feature set.
