Simulates an environment by mapping six image files onto the inner surfaces of a large (or infinitely large) cube.
Use Env Cube to make reflections on a moving surface during an animation if you do not have time to raytrace because it treats the texture placement box as the geometry of the environment. This means changes in the relative size and position of camera, surface, and environment are respected.
For example, you can fake a nice reflection on the surface of an animated shiny car as it drives down a road. This process is known as reflection mapping.
Find this texture in the Create bar. To use this texture, see Simulate reflections with Env Cube.
