The sunlight I used last time was built in and easy to use. Now I'm going over how to more directly control the lighting. This chapter has a lot of information and less hands on type stuff. There's various types of lights with different effects and functions and of course many ways to tweak them. You often have to use a combination of types to create a realistic look.To make a bare light bulb, I used a downward pointing spot light. Then I created a glowing sphere so it looks like the light is coming from the bulb.
