Glowing objects emit colored light on their surroundings. Increasing the glow’s brightness raises the amount of light emitted and whitens the color of the glowing object.
Unlit objects don't emit light and more clearly show their color.
Important
Glowing and unlit objects have no edges and are unaffected by the skybox and surrounding light sources.
Please note that it is recommended to use invisible glowing objects, paired with unlit counterparts to better light your world. We will discuss this in a later tutorial in Artistic Tips.
