To Set Up a Scene for the Light Tracer

This is a typical use case:

1. Create the geometry for an outdoor scene.
2. Add a Skylight to illuminate it.

   One or more spotlights can also work well. If you use the physically based IES Sun or IES Sky lights, using an exposure control is essential.

3. Choose Rendering Advanced Lighting Light Tracer.

   This opens the Render Setup dialog to the Advanced Lighting panel and activates Light Tracer.

4. Adjust the Light Tracer parameters, activate the viewport to render, and then activate the Common panel.
5. Adjust your rendering settings, and then click the Render button at the bottom of the dialog.

   The scene renders with soft-edged shadows and color bleeding.
