Heightmap

A grayscale image becomes the terrain heights. Decoded as 16-bit luma.

The dialog maps the pixel range onto an altitude range, and can resize the project to the image.

Colormap

A color image mapped to blocks by nearest color. Posterization reduces it to N colors, each color being assigned to a material and/or a ground cover.

Layers

.voxelierl files are single layers exported from the Layers panel to be reused.

Layers from another project

Imports every layer of another .voxelier, without touching the terrain.

Schematics

Adds .schem (WorldEdit / Sponge), .bp (Axiom) and .litematic (Litematica) to the library, shared by every project.

3D models

.obj and .glb are voxelized into a .bp saved in the library, at an adjustable resolution. A .glb carries its colors and maps them to the 16 Minecraft wool colors.

Images as objects

The same window voxelizes an image into a slab, one block per pixel in wool colors, laid flat or standing upright.

Mod JAR

Extracts the block IDs and textures of a Minecraft mod JAR to get its textures visible and autocompletion on the mod's block names.

Resource pack

Loads the textures of a .zip texture pack to replace the ones on screen.

WorldPainter world

Converts a .world into a new project at its original dimensions. The dialog picks what to bring over: terrains, ground covers, schematic layers and 3D objects, annotations, biomes.
