Important: The total calculation time depends on the complexity of the Scene and of the chosen ShadowQuality Preset.Indirect Illumination:The Indirect Illumination checkbox enables an additional Calculation of indirect light bounces which increasesthe quality of the final result.5 different Presets are available:- Preview Quality- Low Quality- Medium Quality- High Quality- Highest QualityEnable Color Bleeding:Color bleeding enables the transfer of color between nearby objects, caused by the colored reflection of theindirect illumination option.color bleeding causes a white wall close to a red wall to appear pink because it receives red light fromthe wall.Number of Indirections: the number of indirections defines how many light bounces are calculated. Thedefault value is one with means that only one light bounce is calculated.Important: Higher values produce better quality but increases calculation time.Subdivision: Enabling the subdivision checkbox causes geometry to be refined during the Ambient Occlusioncalculation process. Additional vertices are inserted into the meshes. Thus it is possible to get much moresmooth results on the geometry.2 Presets are available:- Low Quality- High QualityMinimum Edge Length: This value defines the threshold of the subdivision. If the length of an edgebetween two vertices is below this value it won't be subdivided and no additional vertices are added.Caution: Enabling this feature increases calculation time and will also increase the polygon count of theScene.ExamplesSettings:Shadow Quality: Preview Quality
