Indirect Lighting

Indirect Lighting only works with Approximate gather method.

The Indirect Lighting panel contains two options:

• Factor
• Defines how much surrounding objects contribute to light.
• Number of indirect diffuse light bounces.The Gather panel contains settings for the indirect lighting quality.Note that these settings also apply to Environment Lighting and Ambient Occlusion.

The Approximate method gives a much smoother result for the same amount of rendertime, but as its name states, it is only an approximation of the Raytrace method,which implies it might produce some artifactsand it cannot use the sky's texture as the base color.

• Passes
• Set the number of pre-processing passes, between (0 to 10) passes.Keeping the pre-processing passes high will increase render time, but will alsoclear some artifacts and over-occlusions.
• Error
• Pixel Cache
• When enabled, it will keep values of computed pixels to interpolate it with its neighbors.This further speeds up the render, generally without visible loss in quality…
• Correction
• A correction factor to reduce over-occlusion. Ranges between (0.0 to 1.0) correction.
