6.1 Scenethe scene.The Ambient Occlusion calculation is a preprocess and takes place during datapreparation. Calculated Ambient Occlusion results are baked on the geometry’svertices. The smoothness of the Ambient Occlusion depends on the detail levelof a geometry. Therefore VRED offers several ways to increase the quality onlow level geometries, like subdividing triangles and predefined quality presets.» Settings» Save Current: Saves the current setting.» Load from Node: Loads the ambient occlusion settings from the selected geometrynode. Using this method, you can retrieve the settings with which the ambientocclusion was calculated.» Load Settings: Provides a list with the saved settings to select one of them.» Delet Settings: Provides a list with the saved settings to delete one of them.» Direct Illumination» Shadow Quality: Defines the direct shadow quality of the Ambient Occlusion. 6Presets are available:• Preview Quality: 8×8 hemisphere samples (per vertex)• Low Quality: 16×16 hemisphere samples• Medium Quality: 32×32 hemisphere samples• High Quality: 48×48 hemisphere samples• Highest Quality: 64×64 hemisphere samples• Ultra High Quality: 128×128 hemisphere samples» Minimum Distance: Sets the minimum distance of objects to be taken into accountfor the Ambient Occlusion calculation. This value defines totally blackareas where full occlusion takes place.113
