Octane Emission
What is Emission?
"Emission" is a real-world phenomenon: there are many electrons in each atom or molecule, and these electrons can be found at various energy levels. In order for an electron to move from a lower energy level to a higher energy level, it needs to receive energy from the outside. But an electron can go from a higher energy level to a more stable lower energy level required by the "conservation of energy" law and emit photons around it. The frequency of these emitted photons creates the emission spectrum, which is partially visible to human vision (in the range of 400-700 nanometers).
To use a mesh as a light source, the light source mesh surface needs to be either a * Diffuse**, Standard Surface, or * Universal Surface material type.
The Emission types can be connected to the material's Emission input.
