Sun Settings

Sun Settings depend on the SketchUp Sun Settings, and on overrides on the Lighting Options Tab of the IRender Setup Dialog. Other sun settings are made directly in SketchUp .


SketchUp Settings

Location from Model Info in SketchUp
Shadow Settings in SketchUp

Basic shadow and sun settings are made in SketchUp - using the Model Location and Shadow Settings dialog.



IRender Setup Dialog

You can set cloudiness, and override the SketchUp intensities on the Sky Setup Tab .

Light Balance

Sets the dominant source of ambient brightness for the image, the sun and sky, or lamps and other light fixtures.

When this value is modified, a new rendering has to be generated, the resume rendering function will not incorporate the change.

Ambient Light

Ambient Light is the overall brightness of the image, solved during rendering. A lower ambient value will produce more contrast in the rendered image, higher ambient values will flatten the rendering. See: Ambient Light

Settings

  • Show Light Bulbs - Option to display the bulbs in the rendering, this does not influence processing the lighting.
  • Process light bulbs on invisible layers - Includes lighting from sources even if layer is off.
  • Use Watts instead of Lumens for Lamp Units - The unit method for lighting, by default is Lumens.
  • Use Monte Carlo reflections - helps resolve small blurred reflections with bright spots (slow)
  • Use Camera lights - A special lighting condition that will provide illumination when no other lighting is available.

Use Indirect Lighting (reflected light) - See Also: Indirect Lighting

  • None - Light bouncing off of surfaces is not included in the lighting solution for the rendering
  • Standard or Gather - Standard is faster than Gather and will produce essential the same solution
  • # bounces (1-4) - More light bounces from surfaces will increase rendering time but result in a more accurate lighting solution.

Light Balancer

Sets the number of channels to use and default channels for groups of lights. See: Light Balancer

Set light channels

Sets the names of the Light Balancer channels.
