Emissive materials in the rendering

Emissive textures can be used to create surfaces that appear to have an independent light source. Emissive textures can be used for monitors, LED strips and other luminous surfaces. The power of the light source can be set in the texture properties.

How to set up? Render style - Real emissive

False emissive does not actually light up, the surface only gets the color of the material without any shading. Real emissive acts as a light source.
