Initial Setup

  • Open the Asset Editor and go to the Light List.

Adding Dome Light

  • Use the Lights toolbar to add Dome Light:
    • Click the icon, then a spot in the model.

Rendering Adjustments

Dome Light Orientation

    • Use Interactive Render to see changes instantly.

Spherical Option

    • If the ground is not visible, check the "spherical" option.

Additional Features

  • Materials Mockups:
    • Use dome light for visualizing different materials.
  • Depth of Field Effect:
    • Optionally add to models.
