A 3D lighting scheme dictionary specifies the lighting environment applied to a 3D model. Lighting schemes control the overall illumination style, from white lighting to coloured lights to ambient-only lighting.

The named scheme selects a predefined lighting configuration. Authors can choose from standard schemes such as Artwork, White, Day, Night, Hard, Primary, Blue, Red, and Cube, each providing a different visual mood for the model.
