Convert 3D models into buildable Minecraft block data
The Minecraft 3D Model Converter is for GLB, GLTF, OBJ, and STL files that need a block-based build plan. The useful work happens before conversion: choose a practical target size, pick a buildable block palette, then inspect the preview, layers, and export output.
Workflow
- Load a supported 3D model and start with a moderate target size.
- Choose a block palette that fits the model and is realistic for your world.
- Inspect the 3D preview and layer view for missing details, floating blocks, and excessive block counts.
- Export JSON, MCFunction, or Litematica only once the size and material mix look buildable.
Best for
- Statues, logos, props, organic forms, and reference meshes that should become Minecraft builds.
- Comparing several size and palette combinations before starting a large build.
- Builders who need coordinates, layers, or file exports instead of only a screenshot.
Planning notes
- Very detailed models can create more blocks than are practical to place manually.
- A smaller palette often looks cleaner and is easier to gather in survival play.
- Thin model parts may disappear during voxelization; scale the model up or simplify the source mesh.
