Reflections Content Examples

The Reflections Content Example map provides examples on how to adjust the way reflections appear within your levels by using a Reflection Capture Actor (which projects a reflection within the Actor's effect volume or radius). Examples are also shown on how the Roughness, Metallic, and Specular properties of a Material can be used to produce different reflection results.

In addition to tweaking reflection settings, the use of both a Box Reflection Actor and the more commonly used Sphere Reflection Actor are shown with sample effects that can be achieved. Lastly, Scene Capture methods are demonstrated which can be used to capture a fully dynamic cube map or capture an image of the scene on every frame.

Listed below are the examples provided inside the Reflections map:

Example What is Demonstrated
1.1 Reflections Metallic Materials Metallic Materials reflecting objects based on the Metallic and Roughness properties (increasing Metallic property results in more chrome like appearance).
1.2 Reflections Non-Metallic Materials Non-metallic Materials (0.0 for the Metallic property) reflecting objects based on the Roughness and Specular values of the Material.
1.3 Box Reflection Capture Actor (Static) Demonstrates reflection using the Box Reflection Capture Actor which is good for use with interiors that have a box shape.
1.4 Sphere Reflection Capture Actor (Static) The more commonly used Sphere Reflection Capture Actor used to reflect the environment, which blends better and is more flexible than the Box Reflection Capture.
1.5 Screenspace Reflections (Dynamic) Screenspace Reflections are a dynamic Post Process effect that can only reflect what is on screen.
1.6 Scene Capture Cube (Dynamic) Scene Capture Cubes capture a fully dynamic cube map from their location on every frame (these are expensive performance wise and should only be used when absolutely required to achieve a given effect).
1.7 Scene Capture 2D (Dynamic) Scene Capture 2D captures an image of the scene on every frame and projects the image in a Material (they work more like a TV screen receiving an image from a camera and are most commonly used for security camera effects).
