In some projects, you may want a camera that does not show perspective. You want all lines to stay parallel and objects to appear the same size regardless of distance. This is called orthographic mode. In this article, we explain how to set a camera to render in orthographic mode in Blender. We will also look at examples from many different areas, from architectural design and comic art to video games and graphic design.
What Is Orthographic Mode?
Orthographic mode is a camera setting that removes the perspective effect. In this mode, objects do not appear smaller as they get farther away. All lines remain parallel, Just like looking at a blueprint or a technical drawing. Everything is measured exactly and there is no depth illusion. Many architects, designers, and game artists use orthographic mode to create clear, accurate images.
For example, many comic books and cartoons use this style for dramatic effects. The famous comic book style of artists like Frank Miller relies on sharp lines and consistent scale. Similarly, video game artists use orthographic views in strategy games like Age of Empires to create clean and precise visuals. Even some movies, like the symmetrical shots in Wes Anderson films, use similar ideas to make a scene feel more graphic and organized.
When to Use Orthographic Mode
There are many reasons to use orthographic mode. Here are a few common cases:
- Architectural Visualization: Architects use orthographic cameras to create floor plans and technical drawings that show every detail accurately.
- Graphic Design: Designers may use orthographic views to create logos, icons, and illustrations without the distraction of perspective.
- Technical Drawings: Engineers and inventors need images that are true to scale. Orthographic mode helps to deliver precise information.
- Game Development: Many 2D and isometric games use orthographic views to keep a consistent look. For instance, games like Monument Valley use flat designs that are easy to read.
- Animation: Sometimes, a director may choose orthographic views to emphasize a specific style. This can be seen in some experimental animations where the absence of depth creates a unique atmosphere.
Using orthographic mode can give your project a clean, modern look and help you focus on details without the distortion of perspective.
How to Set a Camera to Render in Orthographic Mode in Blender
Follow these simple steps to change your camera to orthographic mode.
1. Select the Camera
In the Outliner panel, look for the camera you want to change. Click on it to select it. You can also click directly on the camera in the 3D Viewport if it is visible.
2. Go to the Camera Properties
On the right side of Blender, you will see the Properties Editor. Click on the camera icon to open the Camera Properties panel. This panel shows all the settings for your selected camera.
3. Change the Camera Type
In the Camera Properties panel, look for the section labeled “Lens.” There is an option for “Type.” By default, this is set to “Perspective.” Click on the dropdown menu and select “Orthographic.”
When you select Orthographic, your camera stops showing depth and perspective. All objects appear in a flat, parallel view.
4. Adjust the Orthographic Scale
After you change the camera type, a new setting called “Orthographic Scale” will appear. This setting controls how much of the scene the camera sees. A larger number means the camera sees more of the scene. Adjust this number until you get the view you like.
For example, if you are creating a floor plan for a house, you might want a high orthographic scale to show the entire room. In contrast, for a close-up technical drawing, you might use a lower scale value.
5. Test the Camera View
Press Numpad 0 to switch to the camera view. Look at your scene to see how it appears with the orthographic setting. The image should have no perspective, and parallel lines remain parallel. If the view is too wide or too narrow, adjust the Orthographic Scale again until you are satisfied.
6. Save Your Settings
Once you are happy with the camera settings, save your project or save these settings to The View Keeper. This way, your changes are not lost, and you can use them later.
Tips and Tricks for Using Orthographic Mode
Using orthographic mode opens up many creative possibilities. Here are some useful tips:
Use Orthographic Mode for Technical Projects
Many technical drawings, such as blueprints and schematics, look best in orthographic view. Try setting up your camera to show a detailed, flat view of your model. This can be especially helpful for architects and engineers who need precise measurements.
Combine Orthographic Mode with The View Keeper
For those using The View Keeper, you can save your orthographic camera settings as a view record. This is very useful if you are working on advanced projects where multiple camera types are needed.
For instance, you might save one record as orthographic mode for architectural or stylistic layouts and another record as perspective mode for character close-ups or cut scenes. Switching between these saved settings is as simple as clicking a record in The View Keeper panel. This saves time and keeps your workflow organized. By setting up multiple view records, you can switch between them during rendering. This technique is often used in animated films and video games to create varied visual styles without the need for multiple cameras.
Experiment with Different Orthographic Scales
The Orthographic Scale setting is key to getting the right view. Experiment with different values to see how much of your scene is visible. You might find that a slightly higher scale gives a more dramatic effect for game art, while a lower scale is perfect for detailed illustrations.
Reference Different Media for Inspiration
Look at a variety of media to see how orthographic views are used. For instance, many classic computer games, such as SimCity or Final Fantasy Tactics, use orthographic views to present information clearly. In graphic design, artists often use orthographic projections to create clean, minimalistic designs. Even in art history, modern artists like Piet Mondrian embraced flat, geometric compositions that resemble orthographic views. Drawing inspiration from these diverse sources can help you understand when and why to use orthographic mode in your projects.
Adjust Other Camera Settings
Changing to orthographic mode is only one step. You may also need to adjust other camera settings, such as clipping values, to ensure your scene appears exactly as you want. Clipping values determine how close or far objects need to be to appear in the render. Make sure these values are set correctly so that no part of your scene is accidentally cut off.
Consider the Purpose of Your Render
The choice between perspective and orthographic mode depends on the final purpose of your render. For visualizations that require depth and realism, perspective mode is best. However, for technical illustrations, diagrams, and certain stylistic choices in animation, orthographic mode provides clarity. Think about what you need to show in your scene and choose accordingly.
Common Uses for Orthographic Renders
Orthographic mode is not just a technical feature; it has many real-world applications. Here are a few common uses:
Architectural Visualizations
Architects often use orthographic views to create floor plans, elevation drawings, and technical diagrams. These views show the design of a building without distortion. For example, a designer working on a modern office space might use an orthographic camera to capture the clean lines and precise details of the layout.
Graphic and Technical Illustrations
Graphic designers and engineers use orthographic projections for creating clear and precise illustrations. This is common in user manuals, instructional guides, and technical documents. An illustrator working on a new product design can use an orthographic view to show all the components in detail.
Video Game Art
Many strategy and simulation games use orthographic views to create a consistent and readable interface. For example, games like Diablo II and League of Legends use similar camera settings to keep the game environment easy to navigate. If you are designing game art, using orthographic mode can help you create a style that is both functional and aesthetically pleasing.
Animation and Storyboarding
Some animated films use orthographic shots to establish scenes or create stylistic contrasts. For instance, a scene might switch to an orthographic view to emphasize a character’s isolation or to provide a technical look in a futuristic setting. Storyboards can benefit from orthographic views because they clearly show the layout of a scene without the complexity of perspective.
Isometric and 2D Game Development
Isometric games, like SimCity or Final Fantasy Tactics, rely on orthographic cameras to maintain a consistent scale and perspective. In these games, every object appears the same size regardless of its position. This allows players to navigate the game world more easily. By setting up an orthographic camera in Blender, you can create art that is perfect for these types of games.
Advanced Techniques with Orthographic Cameras
Once you are comfortable setting a camera to render in orthographic mode, you might want to explore advanced techniques to further enhance your work.
Combining Orthographic and Perspective Views
In some projects, you might use both orthographic and perspective cameras. For example, an animated short might begin with an orthographic shot to introduce a character in a technical style, then switch to perspective mode for dynamic, lifelike action scenes. Setting up multiple cameras in your scene and using a tool like The View Keeper allows you to switch between these modes quickly. This blend can create a unique visual style that stands out.
Creating a Split Screen Effect
Another advanced technique is the split screen effect. You can render a scene using both orthographic and perspective cameras and then combine them in post-production. This method is often used in movies and television to show different points of view simultaneously. For instance, one half of the screen could show a technical diagram in orthographic view, while the other half shows a lively perspective view of the same scene.
Tools like The View Keeper help you render both screens in one go which is much better than rendering the first and going back to change settings in order to render the second screen. Using The View Keeper, all renders can be automatically saved to your folder of choice thereby having them ready for post processing. This technique can be a powerful storytelling tool.
Adjusting Clipping and Scale for Precise Renders
When working with orthographic cameras, pay close attention to clipping settings and the orthographic scale. These values ensure that every part of your scene is visible and accurate. Fine-tune these settings to match the needs of your project. For example, in a technical drawing of a complex machine, you want to make sure that every detail is clear. Adjust the near and far clipping values so that no part of your model is accidentally cut off. Similarly, adjust the orthographic scale until your composition looks balanced and complete.
Experimenting with Lighting and Materials
Even when using an orthographic camera, lighting and materials play a crucial role. Although orthographic views do not show perspective distortion, they can still be very dramatic when lit properly. Experiment with different lighting setups to see how they affect your render. For instance, a flat orthographic view with high contrast lighting can create a bold, graphic look. This style is common in modern graphic design and can be seen in works by contemporary digital artists.
Real-World Inspirations
Different types of media have used flat, orthographic-like views to great effect. Consider how technical drawings in engineering textbooks give clear instructions, or how comic book panels use flat perspectives to focus on storytelling. Video games like Monument Valley and SimCity rely on consistent, flat views for clarity and design. Even in contemporary art, artists sometimes use flat, geometric compositions to create modern, minimalistic works. These examples show that orthographic views are powerful in many contexts.
In graphic design, for example, a designer might use an orthographic projection to create a logo that is simple yet precise. In film, directors sometimes use flat compositions to emphasize the form and structure of a scene. Learning how to set up an orthographic camera in Blender can help you mimic these styles and bring a fresh look to your projects.
Troubleshooting Common Issues
Even with clear steps, you might run into a few issues when setting a camera to render in orthographic mode. Here are some common questions and how to fix them:
- Problem: My scene looks too flat.
This is expected in orthographic mode. If you need depth, try switching to perspective mode for those parts of your project. - Problem: I cannot see all parts of my scene.
Check your clipping settings. Adjust the near and far clipping values in the Camera Properties to ensure nothing is cut off. - Problem: The view does not change when I adjust the orthographic scale.
Make sure you are in Camera View (press Numpad 0) to see the updated settings. - Problem: I am not sure which scale value to use.
Experiment with different orthographic scale values until the view matches your needs. Use reference images or sketches to guide your decision. - Problem: Switching between multiple cameras is exhausting.
Use The View Keeper to save and organize your camera settings. This tool will help you switch views with one click and keep your workflow neat and easy.
