![]() In addition, there are a number of supporting Actors that can be used to simulate real-world camera shots. Like their real-world counterpart, Camera Actors are used to view your Level and create cinematic sequences. Refer to the Sky Lights page to learn more. It regenerates lighting and reflections whenever the corresponding probe's texture updates based on the real-world lighting. If you are developing an Augmented Reality (AR) application, consider using an ARSky Light Actor instead.ĪRSkyLight is a subclass of the SkyLight class that uses real-world environment probes to update reflections. ![]() That means the sky's appearance and its lighting / reflections will match, whether your sky is coming from the atmosphere, layered clouds on top of a skybox, or from distant mountains. The Sky Light captures distant parts of your Level and applies them to the scene as a light source. Refer to the Rectangular Area Lights page to learn more. You can use these to simulate any kind of light sources that have rectangular surface areas, such as windows, televisions, or monitor screens. Rect Lights emit light into the Level from a rectangular plane with a defined width and height. Refer to the Spot Lights page to learn more. Outer Cone Angle, which defines the outer bounds of the Spot Light.įrom the Inner Cone Angle and extending towards the limits of the Outer Cone Angle, the light's intensity falls off, softening around the Spot Light's disc of illumination. Inner Cone Angle, inside which the light achieves full brightness. The Spot Light's shape is defined by two separate cone angles: A Spot Light emits light outward in a conical shape from a single point. Spot Lights work like a stage light or a flashlight. Refer to the Point Lights page to learn more. A Point Light emits light in all directions from its center, which is a single point in the Level. Point Lights work like real-world light bulbs. Refer to the Directional Lights page to learn more. ![]() This means that all shadows cast by this light will be parallel, making this the ideal choice for simulating sunlight. You can learn more about lighting fundamentals in Unreal Engine from the following Unreal Online Learning courses:Ī Directional Light simulates light that is being emitted from a source that is infinitely far away. The following types of Light Actors are available in Unreal Engine: Some Light Actors have a limited area of effect around them, while others affect your entire Level. Refer to the Geometry Brush Actors page to learn more.Īs the name suggests, Light Actors are used to place different types of lights around your Level. Use these to get a rough impression of the size and placement of environment props. The following types of Brush Actors are available in Unreal Engine:īrush Actors are commonly used to quickly prototype environments and block out levels. ![]() These Actors can be changed using the Geometry Editing mode in the Level Editor. Refer to the Skeletal Mesh Actors page to learn more.īrush Actors are a basic type of Actor that displays simple 3D geometry in the scene, such as spheres, cubes, and stairs. Skeletal Mesh Actors are commonly used to represent player characters or NPCs, as well as other animated creatures and complex machinery. These can either be created and exported from external 3D animation applications, or programmed directly in Unreal Engine. The Skeletal Mesh Actor displays an animated mesh whose geometry can be deformed, typically through the use of control points during animation sequences. Refer to the Static Meshes section to learn more. Static Mesh Actors are commonly used to create game worlds or other types of environments. Otherwise, the Actor itself can be moved or changed in other ways during play. A mesh is static if its geometry does not change. Although the name implies that the Actor is static (or unable to move), the "static" refers to the type of mesh used rather than the Actor's ability to move. The Static Mesh Actor is a simple type of Actor that displays a mesh in the Level. Skeletal Mesh Actors, which are typically used for player characters and animated non-player characters (NPCs). Static Mesh Actors, which are used to build levels and environments. Unreal Engine uses two types of mesh Actors: Some plugins and project templates add their own Actors, and certain Actors may not be available for all projects.Ī mesh defines the shape and size of an environment prop or a player character. Note that this is not a comprehensive list of every Actor type available in Unreal Engine. Each section includes links to other pages and resources where you can learn more about these Actors and what you can do with them. The Actors are grouped by purpose and functionality. This page describes the most common types of Actors you will be working with in Unreal Engine.
