Unreal Engine 4 offers a variety of controls to navigate its viewports, including panning, orbiting, and zooming. These controls can be manipulated using a combination of the mouse and keyboard. Users can also adjust the speed of the camera using the Viewport camera speed option. To enable scaled zoom and pan, users need to open the Editor Preferences window and navigate to the Level Editor > Viewports section. In the Controls section, they can locate and enable the Use distance-scaled camera speed setting. This setting allows the camera to orbit around the pivot of selected objects rather than the centre of the screen, making camera movements feel more natural.

What You'll Learn
Using the mouse
Panning in Unreal Engine 4 can be achieved in a variety of ways, including using just the mouse, or a combination of the mouse and keyboard.
To enable scaled zoom and pan, you need to open the Editor Preferences window and navigate to the Level Editor > Viewports section. In the Controls section, locate and enable the "Use distance-scaled camera speed" setting. This will automatically scale the sensitivity of zoom and pan camera operations based on the distance between the selected objects and the camera, resulting in more natural camera movements.
It is worth noting that some users have expressed a desire to customise the mouse controls for navigation and panning, as the default settings may not align with their expectations or preferences. For example, one user suggested using the right mouse button for panning instead of the middle mouse button.
Additionally, when using a Magic Mouse or Magic Track, you will need to adjust the camera speed using the "Viewport camera speed" option, as the RMB + Mouse Scroll Wheel combination will not work for changing the camera speed.

Using the keyboard
Panning in Unreal Engine 4 can be achieved in a few different ways, depending on your preferred setup. Firstly, you can enable scaled zoom and pan by opening the Editor Preferences window, navigating to the Level Editor, and then selecting the Viewports section. Here, you can locate and enable the "Use distance-scaled camera speed" setting. This allows you to control the camera's movement around the pivot of selected objects, rather than the centre of the screen.
Additionally, Unreal Engine supports Maya-style pan, orbit, and zoom viewport controls. This means you can use the F key to focus on a selected object or group of objects. The sensitivity of the zoom and pan camera operations will be automatically scaled based on the distance between the selected objects and the camera, resulting in more natural camera movements.
You can also use keyboard shortcuts to navigate and manipulate the view in Unreal Engine 4. Here are some basic keyboard shortcuts to help you get started:
- Perspective View: Alt + G
- Front View: Alt + H
- Top View: Alt + J
- Side View: Alt + K
- Copy: Ctrl + C
- Cut: Ctrl + X
- Paste: Ctrl + V
- Delete: Delete
- Undo: Ctrl + Z
- Redo: Ctrl + Y
- Select All: Ctrl + A
- Move Selection: Arrow Keys
- Play/Simulate: Alt + P or Alt + S
Beyond these basic shortcuts, Unreal Engine 4 allows you to customise your keyboard shortcuts. You can modify existing shortcuts or create entirely new ones to suit your workflow. To do this, open the Preference tab in the Editor, click on Edit, and then on Keyboard Shortcuts. You can use the Search field to find pre-existing commands and modify them by entering your desired hotkey. If your desired shortcut already exists for another function, a red warning will appear.

Using a combination of the mouse and keyboard
To pan your view in Unreal Engine 4, you can use a combination of the mouse and keyboard. Firstly, ensure you have enabled the secondary click function on your mouse in your system preferences. This will allow you to use the right-click function on your mouse, which is necessary for some of the view controls.
With your mouse, you can pan in the 3D view by using the middle mouse button. This will allow you to move your view around the scene. You can also use the RMB (right mouse button) + Mouse Scroll Wheel to adjust the camera speed, but this may require you to adjust the Viewport camera speed option in the settings.
To enable scaled zoom and pan, you can go to the Editor Preferences window and navigate to the Level Editor > Viewports section. Here, you can locate the "Orbit camera around selection" setting and enable it. This will allow you to use the transform tools to move, rotate, and scale actors in the viewport.
In addition to mouse controls, there are also keyboard shortcuts that can be used in combination with the mouse to navigate the view. For example, you can use the "WASD" keys to move around the view, which may feel natural to those familiar with PC shooter games. The "F" key can be used to focus on a selected object, and the "Ctrl" key in combination with other keys can be used for various functions such as copying, cutting, and pasting.
You can also create your own keyboard shortcuts in Unreal Engine 4. To do this, open the Preferences tab in the Editor and click on Edit, then Keyboard Shortcuts. You can search for pre-existing commands and modify or delete shortcuts as needed.

Enabling scaled zoom and pan
To enable scaled zoom and pan in Unreal Engine 4, you must first open the Editor Preferences window. From there, navigate to the Level Editor > Viewports section. In the Viewports section, you will find the Controls subsection on the right side of the screen. Click on the arrow at the bottom of the Controls subsection to expand it and reveal additional settings.
In the Controls subsection, locate the "Orbit camera around selection" setting. This setting enables the Orbit tool, which is used to orbit the camera around a pivot point. Clicking the box will enable the setting, while clicking the box again will disable it.
With the Orbit tool enabled, you can now use the RMB (Right Mouse Button) to orbit the camera around the pivot point. Additionally, you can always press 'F' to focus on a selected object or group of objects.
The sensitivity of zoom and pan camera operations is scaled automatically with the distance between the selected objects and the camera. This makes camera movements feel more natural, especially when working with objects of varying sizes, such as tiny mechanical parts or large landscapes.

Adjusting the camera speed
Using the Mouse Scroll Wheel:
If you are using a standard mouse, you can adjust the camera speed by scrolling the mouse wheel. Scrolling the wheel forward increases the camera speed, while scrolling it backward decreases the speed. This method provides a quick and intuitive way to adjust the camera speed without interrupting your workflow.
Viewport Camera Speed Option:
When using a Magic Mouse or Magic Track, the RMB + Mouse Scroll Wheel combination may not work for changing the camera speed. In such cases, you can adjust the camera speed using the "Viewport camera speed" option in the settings. This option allows you to customize the camera speed to your preferred level.
Enabling Scaled Zoom and Pan:
To enable scaled zoom and pan in Unreal Engine 4, navigate to the Editor Preferences window. Go to the Level Editor > Viewports section and click on the arrow in the Controls section to expand the settings. Locate the "Use distance-scaled camera speed" setting and enable it by clicking the box. This setting allows the camera to orbit around the selected objects' pivot rather than the centre of the screen, providing a more dynamic view.
Keyboard Controls:
You can also use the keyboard to adjust the camera speed and navigate the viewport. The WASD keys are commonly used for movement, with "W" and "S" controlling forward and backward movement, and "A" and "D" for left and right movement. This setup is familiar to those who play shooter games on the PC, providing a comfortable and intuitive navigation experience.
Smooth Camera Panning:
For smoother camera panning, you can adjust the bEnableCameraLag flag on the Unreal Engine camera boom object (USpringArmComponent). Setting this flag to true allows the camera to lag behind the target position, resulting in smoother movement. You can also adjust the CameraLagSpeed value to control the amount of lag and further refine the smoothness of the camera panning.
