Base Emission

This parameter specifies the base amount of light a material emits (in units of Lumens), which can be modulated using the Emission parameter.

This is used to create light sources.

An example of a 1500 Kelvin blackbody emitter.

RGB: Light based on colour and brightness.
Uniform: A white light with intensity based on value given.
Blackbody: Light is based on the temperature. Measured in Kelvin.
Peak: Defines a band of wavelengths in which the material emits light.
Tabulated: The emission spectrum is specified at regular wavelength intervals, which is useful for entering lab-measured data when a very controlled simulation is required.

Materials which have a base emission attribute:
Glossy Transparent
Diffuse Transmitter
