What is an mcstructure viewer?
On Minecraft Bedrock Edition, the structure block saves a selected region as a .mcstructure file — the Bedrock container for blocks, blockstates, and block entities. It's how builds move between worlds, behavior packs, and adventure maps on Bedrock, console, and mobile.
An mcstructure viewer lets you open those files without loading a world or placing a structure block. Drop one into your browser and Shulkr renders the build in 3D, mapping Bedrock blocks to their Java equivalents so you can inspect layout, dimensions, and contents at a glance.
Behavior-pack workflow
Bedrock keeps structure files inside a behavior pack at BP/structures/<namespace>/<name>.mcstructure. Copy that file out of the pack and preview it here before loading it back in-game with a structure block in Load mode.
When this is useful
- Previewing a Bedrock build on a phone or laptop that isn't running Minecraft.
- Inspecting structures inside a downloaded behavior pack or adventure map.
- Sharing a Bedrock build with someone who plays Java, or moving it across with the converter.
- Counting blocks and estimating materials with the built-in area-measure tool.
Shulkr is fully client-side — your .mcstructure file is parsed and rendered entirely in your browser and never leaves your device.
