Rendering Is Not About the Actual Light

So much about rendering comes down to the materials, it's not about the actual light. Different surfaces have different properties that will absorb or reflect that energy differently. And so for photo realism, light is obviously very important, but it really come down to the material. Now this day and age there's a lot of sort of precepts, i guess, for lack of a better phrase,. But there's like material libraries that you can put in work for figuring out what rente or pavement should look like.
