GENERAL PROPERTIES

  • Shadows: Enables / disables shadow casting
    • Softness: Defines whether the light will have soft shadows or not
    • Radius (m): Defines how soft the shadows will be. Higher values result in softer shadows
  • Assign Container: Select the material from the list that will be assigned as a container for the camera.

The assign container options allows the user to assign a material as the container of the camera. By default, it is set to Global Medium but when a camera is inside an object with a material using medium, the image will render black, unless we assign that specific material to the container of the camera.

EMITTANCE PROPERTIES

  • Efficacy: Defines the energy loss of the emitter. A value of 683 lm/W corresponds to lights without energy loss.
  • Attenuation: Defines the attenuation type of the emitter. For physically accurate results, the default value (Inverse Square) should be used.

CUSTOM LIGHT EVALUATION

Custom light evaluation allows the user to select which components (such as diffuse, translucent, reflectance, transmittance, and SSS) will be evaluated for a given material and light, thus removing unwanted contributions and accelerating render times.
