What it is
VoxelVision (version 4, formerly BlockBlender) is an add-on for Blender, the free 3D program. It converts a model into Minecraft blocks inside Blender and builds its block set from the textures of a Minecraft Java .jar file that you provide.
It exports Sponge .schem files and Axiom blueprints (.bp), and Bedrock .mcstructure files (added as a beta). The developer tested the exports with Axiom, Litematica and WorldEdit. Its generators also build trees, grass, scatter and terrain.
What makers use it for
- Turn a 3D model that you made, or have the rights to use, into a block build.
- Choose the blocks for the conversion with your own palette, including blocks from mods.
- Generate trees, rocks, grass and terrain as blocks, and place them with the modifier stack.
- Export the result and paste it in the game with WorldEdit, FastAsyncWorldEdit or Axiom.

When to pick it
- You already model in Blender, or you have a model and want it as a build.
- You build organic shapes, statues, creatures or vehicles that are slow to place block by block.
- You are fine paying for the full version: the free VV Trial has limited settings.
When another tool fits better
- You do not want to learn Blender: the add-on lives inside it.
- You build by hand from references: WorldEdit or Axiom are the tools for that.
- You make low-poly models for a resource pack, add-on or mod: Blockbench is built for that.
- You will use it for paid work on a small budget: the personal licence is non-commercial, commercial use starts at $69.99.
