Blockbench for Web

Quick summary

Blockbench is a free, open-source 3D editor focused on low-polygon models with a strong emphasis on Minecraft-style assets. It’s distributed under the GPL and is designed to streamline creation of blocky models, textures, and animations for games and other small projects.

Main capabilities

• Animation tools that let you rig and time poses and sequences.
• Texture creation and painting directly within the program or via external image editors.
• Low-poly model building using cuboids to achieve a voxel/Minecraft look.

Modeling and texture workflow

Start a project by specifying the filename, parent model (if any), texture dimensions, and a short description. You can produce standard block models, entity models, and several exportable model types.

• Edit and paint textures either in a 2D texture editor or on the 3D mesh itself; plugins let you connect external pixel-art programs.
• Construct models by adding cubes and adjusting their rotation, origin point, and orientation.
• Import local PNG files to use as texture maps for your models.

Animation and fine-tuning

Blockbench includes tools for animating models and refining motion with curve controls and graph-based editing. These features help you produce smoother, more complex movements, although adding non-cuboid geometry may complicate animation workflows.

• Use the built-in graph editor to polish timing and interpolation for joints and keyframes.
• Add curves to shapes for more organic forms, but be aware this increases rigging and animation complexity.
• Export completed animations for use in other tools or engines.

Export options and interoperability

The editor supports a variety of output formats and integrations so you can move models and animations into different pipelines.

• Export results as OBJ or other generic formats, or render and refine in external 3D suites like Blender and Maya.
• Output directly to Minecraft formats, including dedicated support for Java and Bedrock conventions, and compatible Optifine entity formats.
• Share models and animations on platforms such as Sketchfab or save as JSON for game use.

Who will benefit from it

Blockbench is ideal for modders, mapmakers, and creators who want to produce Minecraft-style assets quickly. Its approachable toolset makes it useful for hobbyists and more advanced users alike who need low-poly modeling with integrated texturing and animation.

Limitations to consider

• The editor’s core design targets cuboid-based models; while curves are possible, they’re harder to work with and can create animation headaches.
• Although usable outside of Minecraft projects, features and format support are strongest for Minecraft-related workflows, so some non-Minecraft uses may feel constrained.
