  4. Set Shadow Softness: Use the “Dark” and “Light” sliders to control how soft or sharp you want your shadows to appear.

Add Artificial Lights with Plugins

If you want more control over your lighting setup, consider using plugins that provide additional lighting options. Here are two popular plugins for adding artificial lights:

Create Realistic Lighting with Material Properties

In addition to using sunlight and artificial lights, you can also enhance the lighting in your SketchUp model by adjusting material properties. Here’s how:

  1. Select an Object: Choose an object or surface in your model that you want to modify.
  2. Edit Material: Right-click on the object and select “Edit” > “Entity Info”. This will open the Entity Info window.
  3. Tweak Properties: In the Entity Info window, navigate to the “Materials” tab and adjust properties such as “Reflectivity”, “Transparency”, and “Emission”. Play around with these settings to achieve the desired lighting effects.

With these techniques, you can now change and enhance the lighting in SketchUp to create stunning visualizations of your designs. Experiment with different lighting setups, plugins, and material properties to achieve the desired atmosphere and realism in your models. Happy rendering!
