Why Rendering Additional Lighting Passes?
One word, to save time, That's two words!
Instead of re-rendering the image with It's component ( Materials ..GI.. etc) we could cut the fat and render only a specific lighting pass.
Lighting passes are direct light, which means we don't need to re-render Indirect Illumination nor the Shaders.
It can be a slow process to render everything from scratch. Imagine 5000 frames!
