Lighting
 
To see or to render a scene or any objects, you must define lights.
 
  • Create Lights
    • Ambient light: Raises the overall light in the scene by increasing the brightness of all objects.
    • Directional light: Casts light in parallel rays from a cylindrical source.
    • Point light: Casts light equally in all directions from a single
    • point. Spot light: Casts light from a cone that can be positioned.
    • Area light: Casts light equally from a specified area.
    • Volume light: Casts light within a specified volume
