Viewport Controls

There are various controls to enable you to navigate the scene, select and manipulate Actors, and change display options while working in the viewports.

For the purposes of this document, you should assume the following abbreviations:

There are a variety of ways in which to navigate the Unreal Editor viewports. Some can be done entirely with the mouse, with the keyboard, or with a variety of combinations between the two.

Some of the controls below are configurable in the Keybindings Editor . Their default state is listed here. If you have made changes to them, they may not match.

Standard

These controls represent the default behavior when clicking and dragging in the viewports with no other keys or buttons pressed. These are also the only controls that can be used to navigate the orthographic viewports.

Game-style

The WASD controls will feel natural to those who are used to playing shooter games on the PC. They are enabled by default and can be used whenever you are holding RMB. This means you will still use RMB to turn the camera while navigating in this way.

These controls are mirrored on the arrow keys and num pad to provide alternate access to them.

All of these controls are only valid in a Perspective viewport, and by default you must hold RMB to use the WASD game-style controls.

Control

Action

W | Numpad8 | Up

Moves the camera forward.

S | Numpad2 | Down

Moves the camera backward.

A | Numpad4 | Left

Moves the camera left.

D | Numpad6 | Right

Moves the camera right.

E | Numpad9 | Page Up

Moves the camera up.

Q | Numpad7 | Page Dn

Moves the camera down.

Z | Numpad1

Zooms the camera out (raises FOV).

C | Numpad3

Zooms the camera in (lowers FOV).

When zooming the camera, holding the RMB will hold the FOV, preventing it from snapping back to its default settings. The FOV will remain until the RMB is released.

When navigating with WASD while holding down the RMB, you can rotate the mouse wheel up to speed up your movement, or rotate the mouse wheel down to slow down your movement.

While using the Magic Mouse or Magic Track you will not be able to change the speed of the camera by using the RMB + Mouse Scroll Wheel, you will need to adjust it using the Viewport camera speed option.

Pan, Orbit, and Zoom

Unreal Editor supports Maya-style pan, orbit, and zoom viewport controls, making it much easier for Maya artists to jump into the tool. If you are unfamiliar, here is a breakdown of the keys:

Command

Description

Alt + LMB + Drag

Tumbles the viewport around a single pivot or point of interest.

Alt + RMB + Drag

Dollies (zooms) the camera toward and away from a single pivot or point of interest.

Alt + MMB + Drag

Tracks the camera left, right, up, and down in the direction of mouse movement.

The use of the F key is not limited to Maya-style controls. You can always press F to focus on a selected object or group of objects!
