In this new tip tutorial we’ll see how we can use Luminous properties to create custom shaped lights. We’ll use Luminous Amount parameter and Luminous Color properties that can be found inside Material Editor, to make a self illuminated toroid that will be our main light source inside the scene. We’ll see how to obtain the best final look using Global Illumination algorithm too. We’ll make some little test using noise procedural maps to control the amount of lighting emitted by different mesh surface area and/or different color area.
