Convert any 3D model or image into Minecraft blocks and bring it to life in-game!

VoxelVision III is an addon made specifically for Blender that turns anything into Minecraft blocks in real time using geometry nodes.
It is great for Minecraft building inspiration and generating gradients. It's easy enough for beginners, although a basic understanding of Blender's interface and functions is recommended. Customizing options are listed in the section below.

Main Feature Overview

Create smooth objects by using the new stair and slab feature!

Stairs and slabs will automatically spawn if a full block cannot be placed inside the given 3D model!

Integrated .schem (Schematic)
and .bp (Axiom Blueprint) exporter to seamlessly bring your creation to life in Minecraft!

The exporter will exactly transfer your selected build from Blender into Minecraft. Tested with Litematica and Axiom!

Addon extension and overhauled UI

VoxelVision III is very customizable. Here are the options for the full version. The free "VV Trial" version only allows you to convert your model into blocks with a limited number of settings.

Three voxelization methods:
"Volume Based", "Precision" and
"Better Hole Resistance"

Sometimes models cannot be converted to blocks with the standard volume-based method if your model has holes in it. The additional "Better Hole Resistance" method tries to solve this problem in most scenarios.

New Asset Generators and many more to come!

Those tools are designed to paint blocks along curves, generate procedural rocks or fog floors. Stay tuned for the future!

Custom block palette, you can decide which blocks are used in your builds!

Blocks are sorted into categories to make selection easy. You can create a mask with your own block palette or even exclude specific blocks that should not appear in your build.

Paint your model in real-time without any texture!

Easily control colors using the included palette. You can also paint with vertex colors or use your own images.

Gradient Toolset

There are 3 dedicated tools for making gradients included in BlockBlender. Radial, linear, and a 4 corner gradient preset.

Bring life into your builds by introducing noise!

Add more block variety by using the noise option. Especially useful to break up monotone patterns.

Guidelines that help you plan your builds and even make it easier to recreate in survival!

Plan your builds using the layer option, so you can build from the bottom up.

View your model's dimensions by displaying length, width, and height information, including for half-sized blocks like slabs. Added a world direction display to help you check the direction your build will be facing when importing a schematic inside of Minecraft.

VoxelVision III Use Cases:

• Convert any 3D model to Minecraft blocks
• Convert any image to blocks
• Model in real-time as your creation is turned into blocks
• Turn text into blocks
• Make complex block gradients easily
• Plan Minecraft builds using the layer option
• Export your models into Minecraft using the built-in export function

VoxelVision III Version Overview:

Limitations of VoxelVision III:

Nothing is perfect, but we want to be transparent about things we know are not working or covered by the addon. For more information, take a look at the following list:

• [Export] The built-in exporter will always export to a .schem file format regardless of the selected Minecraft version! (at no time a .schematic will be exported!) The file format is written in Sponge v2 formatting! (This only applies to the schematic exporter and not the blueprints of Axiom)
• [Export] The currently tested results speak for the usage of Axiom (1.20 -1.21+), Litematica (1.17-1.21+), and Worldedit (1.18-1.21+). Previous versions might not work when trying to import the schematic file, depending on the mod you are using. The newest versions of Minecraft are working precisely and without any problems! (This only applies to the schematic exporter and not the blueprints of Axiom)
• [Coloring] It is not guaranteed that BlockBlender will output a pixel-perfect representation of the texture the model had. Due to the calculation of the closest points, colors can be off by a small amount!
• [Models] Very detailed, thin, or small objects might not be converted entirely. Sometimes blocks are missing as the model might be too thin, and blocks won’t be spawning inside it. You can fix it by increasing the model scale or thickening out the problematic part with the shortcut "Alt+S".
• [Models] The structure of your object is important. Your model must be clean without holes or duplicate vertices. Join your meshes together and use a clean topology and texture for the best results.
• An intermediate knowledge of Blender is recommended for the best usage of BlockBlender V2. By understanding the software first, you will have no problems with the most advanced objects!
• Mistakes and oversights in the block palette can happen and in case you find any block missing, please report it in my discord at any time to make this product even better!
