The Unreal Engine is a popular tool for creating video games and other interactive experiences. One of the key features of the Unreal Engine is the ability to navigate and manipulate 3D spaces and objects within a virtual environment. While using the Unreal Engine, users can pan, orbit, and zoom around a selected object or group of objects in the Level Viewport. This can be done using a combination of keyboard inputs and mouse clicks, with some default controls in place for ease of use. However, users have the ability to customize these controls to their preference. This functionality is particularly useful when working with objects of varying sizes, as it allows for more precise adjustments and a more natural camera movement experience.
| Characteristics | Values |
|---|---|
| Panning in Unreal Engine | Maya-style pan controls are supported, allowing users to press F to focus on a selected object or group of objects. |
| Rotating the viewport | Users can orbit the camera around the pivot of selected objects rather than the centre of the screen. |
| Zooming | Zoom operations are scaled automatically based on the distance between the selected objects and the camera. |
| Navigation methods | The Unreal Editor viewports can be navigated using the mouse, keyboard, or a combination of both. |
| Navigation controls | WASD controls are available, which may feel natural to those who play shooter games on PC. |
| Specific actions | Right-clicking the mouse allows users to rotate, while the mouse wheel enables zooming. |

What You'll Learn
Use the mouse right-click to rotate
The Unreal Engine is a popular choice for developers and offers a range of options for navigating the Unreal Editor viewports. Users can navigate using the mouse, keyboard, or a combination of both.
For users who wish to "Use the mouse right-click to rotate", the following steps can be taken:
Firstly, it is important to ensure that the desired functionality is enabled in the Editor Preferences. To do this, open the Editor Preferences window and navigate to the Level Editor > Viewports section. In the Controls section, ensure that the "Orbit camera around selection" setting is enabled. This setting allows the camera to orbit around the pivot of the selected objects, rather than the centre of the screen.
With this setting enabled, users can now utilise the mouse right-click to rotate functionality. When working with 3D objects or large terrains, right-clicking and holding down the mouse button will allow users to rotate the camera around the selected object or area. This provides a more natural and intuitive way to navigate and interact with the scene.
In addition to the right-click rotation, users can also utilise the mouse wheel to zoom in and out, further enhancing the navigation experience. These controls can be especially useful when dealing with intricate details or when a specific viewpoint is required for tasks such as sculpting or level design.
By following these steps and utilising the mouse right-click to rotate functionality, developers can efficiently navigate and manipulate their projects within the Unreal Engine.

Use the mouse wheel to zoom
Unreal Engine supports Maya-style pan, orbit, and zoom viewport controls. These controls can be used with the mouse, keyboard, or a combination of both.
To use the mouse wheel to zoom in and out, you can define custom events in the 'MyCharacter' blueprint. First, create two custom events: 'ZoomIn' and 'ZoomOut'. These functions will be called when the player scrolls the mouse wheel. Next, create a tick event and two variables: a float variable 'CamBoomLength' to store the updated arm length for the camera, and a float curve variable 'ZoomCurve' to store the curve defined earlier. The default value for 'CamBoomLength' is 800.0, which is the default target arm length.
Now, use an 'FInterp' node to interpolate from the default target arm length to the updated value stored in 'CamBoomLength'. Connect the delta seconds from the event tick to the interp node and set a value for the interp speed.
Move on to adding functionality for the custom zoom events. Extract the float value from the zoom curve using the target arm length as input. Multiply this value by 100.0, as arm lengths are in the range of 100s. Clamp these values between the minimum and maximum float values for your zoom. Based on whether the 'ZoomIn' or 'ZoomOut' event is called, subtract or add this value to the target arm length and store it in the 'CamBoomLength' variable.
Finally, call these events based on player input. Go to your 'MyController' blueprint and add mouse input events for mouse wheel up and mouse wheel down.
By following these steps, you can use the mouse wheel to smoothly zoom in and out in Unreal Engine.

Navigate with the keyboard
There are a variety of ways to navigate the Unreal Editor viewports, including using the keyboard. Here are some tips for navigating with the keyboard in Unreal Engine:
First, open the Preferences tab in the Editor and click on "Edit", then "Keyboard Shortcuts". You can use the Search field to look for pre-existing commands and modify or delete shortcuts as needed.
Some basic keyboard shortcuts for Unreal Engine 4 and 5 include:
- Copy: Ctrl + C
- Cut: Ctrl + X
- Paste: Ctrl + V
- Save in Blueprint: Ctrl + S
- Undo: Ctrl + Z
- Redo: Ctrl + Y
- Select All: Ctrl + A
- Move Selection: Arrow keys
- Open File: F1
- Rename: F2
- Zoom: Mouse wheel up/down
- Rotate: E
- Focus: F (focuses viewport on a selected object)
- View: G (show/hide tools)
You can also enable scaled zoom and pan by opening the Editor Preferences window and navigating to the Level Editor > Viewports section. In the Controls section, click the arrow at the bottom to expand the settings and locate the "Orbit camera around selection" setting. Enable this setting to allow the camera to orbit around the pivot of the selected objects rather than the centre of the screen.
Additionally, the WASD keys can be used to navigate, which may feel more natural to those accustomed to playing shooter games on PC.

Enable scaled zoom and pan in Editor Preferences
To enable scaled zoom and pan in Unreal Engine, you must first open the Editor Preferences window. From there, navigate to the Level Editor > Viewports section. In the Viewports section, you will find a section on the right called Controls. This section contains settings related to the viewport controls, including the ability to enable scaled zoom and pan.
To access these settings, click on the arrow at the bottom of the Controls section to expand it and reveal additional options. Here, you will find the Orbit camera around selection setting. This setting allows the camera to orbit around the selected object(s) rather than the centre of the screen, enabling scaled zoom and pan functionality. To enable this setting, simply click on the box next to it.
Enabling the Orbit camera around selection setting provides more precise control when working with objects of varying sizes, such as small mechanical parts or expansive landscapes. The zoom and pan operations become more sensitive or less sensitive depending on the distance between the selected objects and the camera. This results in more natural camera movements that are better suited to the specific needs of your project.
It is worth noting that the Unreal Editor also supports Maya-style pan, orbit, and zoom viewport controls, which can be useful for artists familiar with Maya. Additionally, the viewports in Unreal Engine can be navigated in multiple ways, including using only the mouse, only the keyboard, or a combination of both.

Use the F key to focus on selected objects
The Unreal Engine is a popular tool for filmmakers, architects, and game designers. It offers a range of keyboard shortcuts, or hotkeys, to help users navigate and work efficiently. One of these shortcuts is the "F" key, which allows users to focus on selected objects in the Level Viewport.
The "F" key is a versatile tool that can be used in conjunction with other keys to perform specific actions. For example, the Shift + F keys can be used together to focus on one or several objects across multiple viewports. This functionality is particularly useful when working with multiple objects or scenes.
In addition to the "F" key, users can also take advantage of other keyboard shortcuts to navigate the Unreal Editor viewports. Some of these shortcuts include using the mouse wheel for zooming in and out, the WASD keys for natural navigation (especially for those familiar with PC shooter games), and the arrow keys for moving selections.
It's important to note that the "F" key is not limited to Maya-style controls. Users can always press "F" to focus on a selected object or group of objects, regardless of their workflow or settings preferences. This functionality ensures that users can easily center their view on specific objects, making it easier to work with objects of varying sizes, such as tiny mechanical parts or large landscapes.
By utilizing the "F" key shortcut, users can quickly and efficiently focus their camera on selected objects, streamlining their workflow and enhancing their overall experience with the Unreal Engine.
