Rendering in SketchUp: From Modeling to Presentation for Architecture, Landscape Architecture and Interior Design

Shaderlight Lighting Options

Shaderlight uses the same basic lighting system outlined in Chapter 24. This includes using point, spot, IES lighting profiles, and light-emitting materials (LEM) (Fig. 29.2, Fig. 29.3). The placement and use of those lights follows the universal method outlined in that chapter. Shaderlight also included two unique options:

• Skylight portal
• Area lights

Skylight Portals

This unique feature offers an exciting way to light a scene. The skylight is a square surface light placed over windows and open portals. It samples exterior lighting and streams it into the scene, just as with a real skylight or window (Fig. 29.6, Fig. 29.7).
