In this tutorial, we’ll walk through the process of creating 2D pixel art style isometric sprites from a 3D model using Blender. Isometric views are often used in games and applications for creating top-down, three-dimensional effects with a 2D representation. By following the steps below, you’ll learn how to generate pixel art style isometric sprites that can be used for game development, animations, or art projects. We’ll be working with a car model, but feel free to use any 3D model you like.
In this tutorial, we’ll walk through the process of creating 2D pixel art style isometric sprites from a 3D model using Blender. Isometric views are often used in games and applications for creating top-down, three-dimensional effects with a 2D representation.
Step 1: Preparing Your Model
1. Select the car model (or whatever model you are using).
2. Right-click and under the Object menu and choose Set Origin > Origin to Geometry. This will center the origin of the mesh to ensure proper rotation and scaling.
3. Open the Properties Panel (press N) and open the View tab.
4. Check the box for Lock Camera to View. This ensures that as you move around the viewport, the camera will follow your movements.
Step 2: Set Up the Camera for Isometric View
1. Select the camera in your scene.
2. In the Object Tab under Location, set the following values: X: 10, Y: -10, Z: 10. For the Rotation values: X: 54.736, Y: 0, Z: 45.
3. In the Object Data Properties tab, change the camera’s Type to Orthographic (this eliminates perspective and gives you a true isometric view).
4. Go to the Render Properties panel.
5. Under the Film section, check the box for Transparent so the background is transparent.
6. In the Output Properties tab, set the resolution to 256 x 256 for both the X and Y axes (or whatever size you need).
7. Press 0 on the numpad to enter Camera View.
8. Move and scale the car model so it fits comfortably within the camera view.
Step 3: Creating the Pixel Art Look
1. Select the model.
2. In the Shading Workspace, add a Shader to RGB node between the BSDF Shader and the Material Output. [convertor]
3. Add a Color Ramp between the Shader to RGB and Material Output nodes.
4. Change the interpolation mode of the Color Ramp to Constant for sharper shadows. You can use this to tweak the highlight intensity.
5. Under Render Properties, open the Film section and set the Filter Size to 0.01. Under the Color Management section, change the View Transform to “Standard”.
7. Set up your lighting and render your image so you can see it in the Compositing workspace.
8. Open the Compositing workspace and activate Use Nodes.
9. Add a Scale node between the Render Layers node and the Composite and Viewer nodes.
10. Add a Value node and connect it to the X- and Y of the Scale node. Change the Value to 0.2.
11. Add a Pixelate node between the Scale node and Composite node.
12. Duplicate the Scale and Value node and place them between the Pixelate and Composite and Viewer nodes.
13. Change the second Value node to 5.
14. Now, you can see the pixel art style being applied to your model.
Step 4: Animating the Car
1. In the Animation workspace, make sure you are on frame 1 on the timeline.
2. Select the model and insert a keyframe for Location, Rotation, Scale by pressing I.
3. Move to frame 2 and rotate the model 45 degrees along the Z-axis. Insert another keyframe (press I again).
4. Repeat this process through frame 8 to complete a full 360-degree rotation.
5. Under the Output Properties tab, set the End Frame to 8.
6. In the Output section, select PNG and RGBA to include transparency.
7. Choose the output folder where the frames will be saved.
8. Render the animation by going to Render > Render Animation.
Step 5: Setting Up the Sprite Sheet
1. Open Affinity Photo or any photo editor of your choice.
2. Make a new document that will be large enough to contain all the sprites. You can do this with columns and rows or just use one long sprite sheet. Make sure you are using a transparent background. [1024, 512]
3. Drag all 8 images into the editor.
4. Snap each separate image into place. Using guides will make it easier. [256, 512, 768]
5. Export the PNG for use in your game engine.
Conclusion
You’ve now successfully created 2D pixel art style isometric sprites from a 3D model in Blender. These steps can be adapted to any model, and you can tweak the settings to achieve different visual effects, such as adding more frames for smoother animations or experimenting with different shadow styles for pixel art. By mastering this technique, you can easily generate sprites for games, animations, or even digital art projects.
