How to Use Blockbench to Create Custom Minecraft Models Blockbench is a free, powerful low-poly 3D modeling software designed specifically for creating custom Minecraft assets. It is so effective that even Mojang uses it internally to design and animate new in-game mobs. Whether you want to add custom items, specialized blocks, or entirely new entities, Blockbench simplifies the process by combining modeling, texturing, and animating into a single user-friendly interface.
This guide breaks down the complete pipeline for creating your first custom model and bringing it directly into your Minecraft world. Step 1: Set Up Your Project Format
Before placing your first block, you must configure Blockbench to output the correct file type for your specific edition of Minecraft.
Download the App: Visit the official Blockbench Wiki or homepage to download the program for Windows, macOS, Linux, or use the web-browser version.
Select the Format: Launch the application. The start screen offers several project formats.
Choose Java Block/Item if you are designing custom tools, items, or decorative blocks via Java Resource Packs.
Choose Bedrock Model if you are developing add-ons for the Bedrock Edition.
Choose Modded Entity if you are constructing custom mobs for Java mods like GeckoLib or MCreator.
Configure Project Settings: A prompt will ask for a file name and model identifier. Ensure you check Box UV. This setting auto-unwraps your 3D geometry onto a flat 2D texture, making pixel-art painting drastically easier. Step 2: Build with Cubes and Bones
Minecraft utilizes a strict low-poly aesthetic. Models are built entirely out of rectangular prisms (cubes).
Add Elements: Click the Add Cube button in the outliner panel to place a base block into your 3D viewport.
Transform Geometry: Use the three main transformation tools located in the top toolbar: Move (V): Shifts your cube along the X, Y, and Z axes.
Resize (S): Stretches or shrinks the cube to form thin blades, wide plates, or thick stems.
Rotate ®: Rotates the element. Note: Java blocks have strict rotation limits (increments of 22.5 degrees on a single axis), so build aligned to the grid whenever possible.
Group into Groups/Bones: Right-click in your outliner panel to create a new folder (called a group or a “Bone”). Drag individual cubes into this folder. If you are creating an entity, grouping parts (e.g., keeping all parts of an arm together) allows you to rotate the entire group as a single joint. Step 3: Map and Paint Your Texture
Once your physical 3D shape is complete, you need to apply textures.
Create a Texture Template: Head to the Textures panel on the left sidebar and click Create Texture. Blockbench will calculate the size of your elements and automatically stitch together a clean, blank layout map.
Switch to Paint Mode: Toggle from “Design” mode to Paint mode in the top-right corner of the interface. This unlocks a digital art toolkit right inside the viewport.
Apply Color and Shading: Use the brush, paint bucket, and eraser tools to style your asset. To nail the signature Minecraft look: Use a restrictive color palette. Avoid heavy blending; draw distinct pixel clusters instead.
Sketch basic color blocks first, then manually add highlights and shadows to give the flat cubes visual depth. Step 4: Adjust In-Game Display Settings
If you are building a Java item or block, you must define how it looks when interacting with players.
