In this beginner Blender tutorial you will learn how to set up Blender to make voxel art models for your projects and games.
Why learn Voxel Art?
Voxel art has become an extremely popular form of art style in recent years. It has been used for many things including some of the great images you see on Mega Voxels to hit games like Crossy Road and Rodeo Stampede. Of course why do so many people love making voxel art? Because its fast and easy. It is literally like building with blocks!
Today there are a variety of software choices for creating voxel art, but in this tutorial we will be using Blender. Blender is the most widely used 3D modeling software on the planet. Because of its Open-Source nature, new features are constantly being added and best of all its free for personal and commercial use!
If you need help installing Blender, view our previous tutorial How to Install Blender. There you can find a step by step tutorial on getting Blender running on your computer.
What is a voxel in Blender?
When you hear the word voxel, think cube. Voxel art is the art of making things with cubes. Now when you work with traditional voxel editors like MagicaVoxel, they only support making your models with voxels, which are 3D
cubes.
However when you work with a 3D modeling software like Blender, you have access to many different shapes including Spheres and Planes. This is important to know because you don’t have to learn a million commands to make voxel art in Blender. And as you continue learning the software you will discover hundreds of different modeling tools and features. Keep in mind, you only really need to learn how to work with cubes to make voxel art. So when we create our models in blender we will only be using the Cube mesh.
Create a New File in Blender
Once you install Blender you will first need to create a new file to store your voxel models inside of. Like almost every voxel editor, Blender uses scenes. A single scene can contain multiple models. Blender then saves this file as a .blend file.
So once you open Blender go ahead and double click the General option under New File on the start screen.
Creating your first voxel in Blender
Once you create a new file, Blender will automatically add a cube to the center of the scene. If you don’t see a cube, you can create one very easily. Simply make sure Object Mode is selected on the top left of the window. To the right of that click on the menu item titled Add. To create a cube click Add > Mesh > Cube.
Ok, we almost have our first voxel, but there is one more thing to do. A voxel must have a dimension of 1 unit on all 3 axis. In pixel art, a pixel is the smallest element in an image. Likewise a voxel is the smallest element in a voxel model. Therefore the dimensions of the cube has to be 1x1x1. To see the dimensions of the cube, click on the cube and then press the N key.
If you notice, under the Dimensions section, the dimensions are set to 2x2x2. Go ahead and type in 1 for the X, Y, and Z.
Congratulations! You just created your first voxel. Now lets set up some snapping to so that are voxel cube aligns itself to the grid.
Setting Up Snapping
An important aspect of voxel art is that everything perfectly aligns to the grid. So let’s set that up now.
To turn on snapping simply click the magnet icon at the top of the viewport.
Now that you have snapping on the grid enabled, test it out by pressing the G key and clicking to move the model around. The only thing you’ll probably notice is as you drag it around it isn’t snapping perfectly to the grid. In order to snap it perfectly to the grid we must first change the Origin of the object. By default the origin of a cube is placed in the center of the cube. That is why the cube appears to go half ways on the grid.
So to fix that we will move the object origin to the corner of the cube. Press the Tab key to go into Edit Mode. When in edit mode click one of the vertices on the corner.
After you have the vertex for the model selected, go to menu on the top left and click Mesh > Snap > Cursor to Selected.
This positions the 3D cursor at the same position of the vertex we selected earlier. Now press tab again to go back into Object Mode. Again at the top left go to Object > Set Origin > Origin to 3D Cursor.
What this command is doing is setting origin of our cube, which was originally in the center, to the position of the vertex we selected earlier.
Now if you try moving your cube again you’ll notice that the cube is still not snapping perfectly to the grid. This is because snapping works by snapping objects in Grid increments, not necessarily to the grid lines. The good news is that its very easy to modify. To fix that we need to go to the snapping popover at the top of the viewport. Click on the checkbox that says Absolute Grid Snap.
Now instead of moving objects by meter it will move the object to the closest meter matching the grid inside of blender just like you see in other popular voxel editors.
Turn on the Orthographic Camera View
One last touch that is missing is the Orthographic camera view. It’s a well known fact that voxel art looks its best when using an orthographic camera view. Its also a lot easier to work with. When you first create a new file in blender though, the camera is set to a Perspective camera view.
What we want is actually what is called an Orthographic camera view. This makes all edges perfectly parallel to each other. The image below is an example of this.
To Change this go into your camera view by clicking View > Perspective/Orthographic.
Where to go from here
You have now set up your Blender environment for creating voxel art. For more in depth tutorials on how to create voxel art inside of Blender check out our Blender Tutorials.
