What is a Litematica viewer?
Litematica is a popular Minecraft mod for printing and following schematic builds in survival. It saves a selected region as a .litematic file containing every block, blockstate, and subregion, readable only by the mod itself by default.
A Litematica viewer lets you open those files outside the game. Drop one into your browser and Shulkr renders the build in 3D with the same per-block detail you'd see in-game: stair orientations, waterlogged variants, redstone components, and Create mod blocks all rendered accurately.
Built around Litematica's workflow
Litematica players don't just look at a build. They print it. Shulkr's slicer mode mirrors the mod's printer / layer mode: step through the schematic one horizontal layer at a time and place blocks in survival without alt-tabbing. Switch the slice axis to plan walls and pillars vertically, exactly as you would set the rendering layers in-game.
- Material list. Hold
Ctrland drag across a layer to get a full per-block-type count for the selection, the same breakdown Litematica's material list gives you, for sizing a shopping trip before you build. - Subregions. Shulkr reads every subregion stored in a
.litematicand assembles them into a single build, so multi-region schematics open in one piece instead of scattered fragments. - Blockstates and block entities. Stair facings, slab halves, waterlogged variants, sign text, and container contents are all preserved, so what you preview matches what the printer will place.
When this is useful
- Previewing a downloaded schematic before launching Minecraft, especially on a different device than your gaming PC.
- Sharing a build with someone who doesn't have the Litematica mod installed.
- Stepping through a build layer by layer while you place blocks in survival, without alt-tabbing out of the game.
- Counting blocks and estimating materials for a region using the built-in area-measure tool.
Shulkr is fully client-side. Your .litematic file is parsed and rendered entirely in your browser and never leaves your device.
