          Using Cameras

          A How To Guide for Finding Actors in your Scenes in Unreal Engine 4.

          This "How To" series covers working with and placing Cameras in Unreal Engine 4. A Camera can be used by itself and placed directly into a level or it can be a part of a Blueprint (for instance to provide a perspective for the player when flying a plane, driving a car, or controlling a character).

          Placing a Camera Actor can be done by dragging a Camera Actor into your level from Modes Menu.

          You can use the Search Bar to find the Camera Actor or look under the All Classess section.

          You can also Right-click in the Level Viewport and use the context menu by selecting Place Actor then selecting the Camera Actor.

          When a Camera is placed in your level, you will notice that a picture-in-picture window is added to the Viewport which represents the viewing angle of the Camera. The name of the Camera is also listed in to center top portion of the window and the option to pin the window (keeping it on screen when clicking off the Camera) is represented by a pin icon in the lower left corner of the window.

          With a Camera selected, you will notice that the Details panel becomes populated with settings that pertain to the Camera.

          Below is an overview of each section in the Details panel for a Camera Actor:

          Property

          Description

          Transform

          This section represents the location of the Camera in the world.

          Camera Settings

          This section allows you to modify the type of projection used by the camera, field of view, aspect ratio, and post process blending.

          Auto Player Activation

          Specifies which Player Controller, if any, should automatically use this Camera when the controller is active.

          Film

          In this section, you can apply film effects such as Tint, Saturation, or Contrast. See also Film .

          Scene Color

          Used to apply effects to the camera. See also Scene Color .

          Bloom

          This simulates the effects the eye perceives when viewing bright objects. See also Bloom .

          Light Propagation Volume

          Used to achieve Global Illumination (GI) in Real-time. See also Light Propagation Volumes .

          Ambient Cubemap

          This lights the scene from a provided image. See also Ambient Cubemap .

          Auto Exposure

          This simulates the human eye adjusting to bright/dark areas. See also Auto Exposure .

          Lens Flares

          This simulates the scattering of light when viewing bright objects through imperfections found in camera lenses. See also Lens Flares .

          Ambient Occlusion

          This is an effect that approximates the attenuation of light due to occlusion. See also Ambient Occlusion .

          Global Illumination

          Used to affect the indirect lighting contribution coming from Lightmass in order to alter a scene's brightness, color, or tint. See also Global Illumination .

          Depth Of Field

          This is used to apply a blur effect to a scene based on distance in front or behind a focal point. See also Depth Of Field .

          Motion Blur

          Used to generate a Motion Blur effect that blurs objects based on its motion. See also Motion Blur .

          Misc

          This is used to apply Blendables (screen overlays), set Anti-Aliasing methods or Screen Percentage options for the Camera. See also Blendables , Screen Percentage , or AA Method .

          Screen Space Reflections

          This is an effect which is enabled by default that alters the appearance of objects on the surface of Materials. See also Screen Space Reflection .

          Activation

          This determines whether or not the Camera is automatically enabled or not.

          Tags

          This allows you to place Tags on the Actor.

          Actor

          This is information pertaining to the Camera Actor itself.

          Blueprint

          This allows you to turn the Actor into a Blueprint or add Events to the Level Blueprint for the Actor.

          For information on using Cameras for cinematic purposes, refer to Matinee How-To's documentation and the Camera sections. The Sequencer Subway is also an excellent resource for a sample cutscene and how it was constructed.

          Now that you have an understanding of how to place a Camera Actor in your level and some of the settings used to alter its look, the examples below provide some ways in which you can use Camera including how to use a Camera as a viewpoint for a player, how to use a Camera Component as part of a Blueprint, how to use a Spring Arm Component with a Camera Component (typically used for creating Third Person perspectives), as well as how to switch between Cameras during gameplay.

          Using Spring Arm Components

          The Spring Arm component is used to automatically control how the camera handles situations where it becomes obstructed.

          Welcome to the new Unreal Engine 4 Documentation site!

          We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

          We'll be sure to let you know when the new system is up and running.
