Turn an image into a build

Pixel art vs. a 3D build

Pixel art maps each region of an image to the closest matching block and lays the result out as a flat wall. It's a direct colour match — the output looks like the input from one angle and like a wall from every other.

A 3D build reconstructs depth first. The image becomes a textured 3D model, that model is voxelized into a block grid, and each surface is matched to the Minecraft block whose texture is closest. The result is a structure you can walk around and into. That's what image-to-build generation does here.

How the conversion works

1. Depth reconstruction. The image is turned into a textured 3D mesh — the model infers the geometry the photo or render only shows one side of.
2. Voxelization. The mesh is sampled onto a block grid at your chosen resolution. Higher resolution keeps more detail and costs proportionally more blocks.
3. Block matching. Each voxel's surface colour is compared against the real texture of every block in the palette, and the closest is chosen — which is why the output uses the blocks a builder would, not a solid mass of concrete.
4. Export. The block grid is written out as a schematic in whichever format your setup reads.

What converts well

• One clear subject filling most of the frame. A building, a vehicle, a statue — not a landscape with six things in it.
• A three-quarter view. Straight-on shots hide depth, and the reconstruction has to guess more.
• Even lighting. Hard shadows get read as dark material and end up as dark blocks.
• A plain background. Busy backgrounds bleed into the silhouette.
• Chunky forms. Anything thinner than a block at your chosen resolution can't survive voxelization — think about how the shape reads at 64 blocks tall, not at full photo resolution.

Picking a resolution

Resolution is the single biggest lever on the result. Too low and the subject stops being recognisable; too high and you get a hundred-thousand-block model that's slow to paste and impossible to build in survival. Start in the middle, look at the preview, and regenerate — it's much faster than fixing detail by hand afterwards.

Cleaning up afterwards

Generated output is a starting point, not a finished build. Open it in the studio to swap materials across a whole region, cut away the parts the reconstruction guessed wrong, flatten a base so it sits properly on terrain, and scale or mirror the result. Then export and import it into your world.

The reverse: a screenshot back into blocks

If your image is a vanilla Minecraft screenshot rather than an outside picture, there's a more exact route. Voxellens solves the camera, matches every visible block face against the known texture set, and reconstructs the actual block positions — recovering the build rather than approximating it.
