Emission defines how light is emitted from the surface, allowing any surface to become a light source. The Emissive map is responsible for simulating the light emission on the material.

This map will be useful for objects that should shine in the Scene. But the Emissive map only simulates the luminosity; and it will not affect other objects unless Lightmapping technology is used.

These may be distant light sources for which it is not necessary to calculate their illumination. This map does not load the game engine, but the object lights up. Emissive map is used for creation materials of neon and fluorescent colors.

The Emissive map shows which areas of our material should glow and which should not.
