Axion v0.2.13 adds two new capabilities to the hotbar, reworks how Move
visualises its source region on 26.x, and improves preview rendering across
every supported range.
Compatibility Notice
The Axion network protocol stays at version 12, so v0.2.13 negotiates with
v0.2.11+ counterparts. Updating the Fabric mod and Paper plugin together is
still recommended.
Highlights
Move Source Glass Ghosts (26.1.2 / 26.2)
- Move now replaces each non-air cell in the source region with light grey
stained glass, rendered as a textured ghost through the GPU preview pipeline.
The glass shell lets terrain behind and around the departing blocks show
through while clearly marking what is leaving. - The ghost shell is computed via surface topology — only boundary cells are
rendered, keeping the interior transparent. - 1.21.11 and below keep the existing overlay fallback. The new glass path
requires26.2's depth-aware translucent pipeline and26.1.2shares the
same rendering backend.
Phantom Capability
- Added Phantom mode, a new toggle in the Alt hotbar menu (bound to a
configurable key, default unbound). When active, the player walks over
tripwires, pressure plates, sculk sensors, and redstone ore without
triggering them, and cobwebs no longer slow movement. - Backed by
PhantomServiceand five targeted mixins that suppress activation
onAbstractPressurePlateBlock,TripwireBlock,SculkSensorBlock,
RedstoneOreBlock, andCobwebBlock. - Includes Chinese (zh_cn) localisation.
No Updates Capability (Placeholder)
- Added No Updates to the hotbar capability list as a placeholder entry
with a "Not yet implemented" tooltip. The slot is reserved for a future
feature that will suppress block updates from Axion operations.
Preview Side Culling and Visualisation
- The scrolling preview now culls non-visible sides. A
PreviewOcclusionPolicy
evaluates whether each neighbour should be reported as air to the tessellator:
identical translucent blocks remain in the occlusion group so vanilla glass
face-culling removes their shared face, while opaque neighbours block faces
normally and non-opaque non-group neighbours are treated as air. ChunkMeshTessellatorcross-section neighbour lookups now read adjacent
16×16 section arrays to determine interior cells correctly across chunk
boundaries, and a cell below a non-opaque block (e.g. tall grass) is no
longer falsely classified as interior.PreviewStateHaloretains only surface cells plus their immediate six
neighbours, avoiding unnecessary expansion of deep interior states.- Selection filled boxes (
PulsingCuboidRenderer) now cull back faces based on
camera position, leaving only the walls actually facing the viewer for a
cleaner look similar to other modern building tools. - The scrolling repeat preview renders a single global aggregate outline across
all committed segments plus the active segment, eliminating internal face
bleed that occurred with per-segment outlines. PreviewTranslucencySortPolicyprovides camera-dependent ordering for 26.x
GPU meshes, accounting for preview translation delta so scrolling the preview
does not break translucency sorting.
Preview Identity and Scene Depth
PreviewBlockIdentityPolicynormalises server-obfuscated block identities in
preview rendering while preserving captured air/non-air occupancy. The move-
source glass replacement tag is explicitly exempted from normalisation.MoveSourceRenderStateandMoveSourceRenderInvalidatorsuppress vanilla
chunk baking at the source origin during a Move preview, preventing visual
double-exposure of the departing blocks.- Added
PreservedSceneDepthhandlers for 26.x that copy the world depth
buffer before the hand is cleared, enabling the late preview pass on 26.2's
submit-node rendering path.
Build and Toolchain
gradle.propertiesnow documents that build-axion.sh overrides version
properties per range.- Added
ClientThreadCleanupSchedulerfor thread-boundary-safe cleanup of
render resources. - New unit tests covering
PreviewOcclusionPolicy,PreviewSectionTransform,
PreviewBlockIdentityPolicy, andPreviewVisualPolicy.
Known Issues
- "No Updates" capability is listed in the hotbar UI but has no backend
implementation yet. Activating it is a no-op.
Release Artifacts
