Changelog

Shulkr is no longer just a viewer — you can now build and edit Minecraft schematics right in your browser.

Build tools

• Place, erase, and pick blocks with a full block palette (search + categories)
• Line and Rectangle tools to lay straight runs and outlines in one stroke
• Drag to paint — sweep place or erase across a surface in a single, undoable action
• Block connections (fences, walls, panes, rails, redstone) resolve automatically as you build

Selection & operations

• Drag a box to select a region, then Fill, Replace, Hollow, Walls, Stack, or Move it
• Copy / cut / paste, and save reusable pieces to your blueprint library
• Click a single block to inspect — and edit its state (facing, slab type, waterlogged…) from a live form

Cameras

• Perspective free-orbit, Isometric (four corner views), and a noclip Explore fly-through

Save & share

• Auto-save keeps your work between sessions; save and reopen projects as .shulkr files
• Export to .litematic, .schem, or .nbt
• New "Open in editor" button in the viewer — jump straight from any schematic you're viewing into the editor

The editor is desktop-only for now. Try it →

Viewer controls

• Right-click to pan in overview mode — drag with the left button to orbit, the right button to pan, and the wheel to zoom
• Minecraft-style keybindings in explore mode — Space / Shift to fly up and down, hold C for slow precision movement, with flight speed that scales to the size of the build
• Layer mode now rotates with Q / E
• Redesigned keyboard hint panel that lights up each key as you press it

Ground grid

• Crisper, redesigned grid that stays clean at any distance — no more dense clutter on large builds when zoomed out
• New Show grid toggle in the Configuration footer

Performance

• Optimized the 3D viewer to render more efficiently, especially on high-resolution and lower-end devices

Fixes

• A handful of bug fixes, including clearer messages when a file can't be read or is corrupt

Convert between schematic formats

• New Export menu in the viewer's top bar — download any open schematic as .nbt, .schem, or .litematic
• Convert freely between the three Java formats — block states, container contents, sign text, and loot tables round-trip losslessly
• New .mcstructure (alpha) export for Bedrock Edition's structure block — convert Java schematics for use in Bedrock

Block-entity inspector

• Selected blocks now surface their normalized block-entity data in the sidebar
• See chest contents (slot, count, item name, custom name), sign text (front and back, with color and glow), custom names, and loot-table references at a glance
• New "Show raw NBT" toggle in the Configuration footer — reveal the literal parsed NBT for any selected block, useful for debugging or understanding format quirks

Materials list

• New Materials tab in the viewer — see every block in your schematic and how much of each you'll need
• Each row shows a small inventory-style icon, the block name, and its count
• Filter the list by block name to quickly find a specific material
• Sort by Most used (default) or A → Z
• Non-vanilla blocks show their mod namespace (e.g. create) as an inline badge

Minecraft-inspired redesign

• Refreshed the UI with a more Minecraft-y feel — headings now use a pixel font and the palette has a subtler, warmer tone
• The viewer now shares the same top bar as the rest of the app, with the file name and back button promoted into it

Mod support

• Load and inspect Create-based blueprints directly in the viewer
• Supported mods now include Create, Create: Simulated, Create: Aeronautics, and Create: Offroad
• Open schematic files directly from supported URL links using the url query parameter

Bug fixes

• Improved water rendering for flowing water, waterlogged blocks, and mixed block-and-fluid details
• Fixed many small rendering and loading issues

Mobile-friendly viewer

• The sidebar becomes a swipeable bottom sheet on touch devices with snap-to-collapse, half, and full-expanded positions
• Canvas now takes the full screen on mobile for a much better viewing experience

Touch controls

• Overview mode — one-finger orbit, two-finger pinch to zoom (works out of the box)
• Layer mode — one-finger pan, two-finger pinch to zoom; layer navigation buttons remain on-screen for quick scrubbing

Explore mode on mobile

• Explore (noclip first-person) mode is hidden on touch devices since it requires pointer lock and a keyboard — the viewer falls back to Overview automatically

UI clean-up

• Keyboard shortcut HUDs are hidden on touch devices to save screen space
• Layer navigation buttons are repositioned to avoid overlapping with the bottom sheet

New schematic formats

• .nbt — Vanilla structure files from Minecraft Java Edition
• .mcstructure — Vanilla structure files from Minecraft Bedrock Edition (experimental)

Import from URL

• Load schematics from a direct URL (useful for direct links to schematics eg: discord, etc)

Sample schematics

• Try the viewer instantly with built-in sample builds
• Includes a windmill, a small base, and a super smelter

Landing page

• Redesigned landing page with view mode presentations, supported formats section, and FAQ
• Drag and drop now works both on the landing page and while viewing a schematic

Changelog page

• Added this changelog page, each release is documented here

Viewer

• Three view modes — Overview (orbit with auto-rotation), Explore (first-person noclip with WASD), and Layer (slice through X, Y, or Z axes)
• Click any block to inspect its type and coordinates
• Ctrl+drag to measure distances between blocks
• Biome-accurate foliage and water tinting
• Light and dark theme support

Supported formats

• .litematic — Litematica mod schematics
• .schem — WorldEdit schematics

Privacy

• Everything runs client-side — no files are uploaded to any server
