This chapter has three sections covering the overall process of setting light:

  • Composing Light Tools: Tools and suggestions for adjusting light
  • Composing Light Strategies: Guides for setting light based on model types
  • Composing the Light: A step-by-step outline of the process

Using the SketchUp Shadow menu to set lighting is essential for most exterior renderings (Fig. 18.4). Although some IRPs have image-based lighting ...
