9 MATERIALS REFERENCE» Contrast: Separates the light and dark color values further from each other.» Brightness: Raises the color value of the whole HDR-Image.» Saturation: Sets the HDR-Image’s saturation.» Reflected Saturation: Sets the HDR-Image’s saturation for reflections of the HDR-Image in any surface.» Transformation With transformation parameters the source of spherical projectionof the SkylightMaterial can be set.» Environment Size: Sets the radius of the projection sphere. The projection spheremust enclose all objects using a material having this SkylightMaterial as environmentshader assigned. All objects that are outside of the projection sphere using aTruelight Material with this SkylightMaterial as input channel, will not be renderedproperly.» Center: Defines the projection sphere’s center position.» Get from Object: Sets the projection sphere’s center. To center the projectionpivot automatically, select an object and press ”Get Center”. The selectedobject’s center will now be used as projection sphere’s pivot.» Rotate X, Y, Z: Sets the SkylightMaterial’s orientation.» Scale X, Y, Z: Sets the SkylightMaterial’s size. With the scale value the imageprojection can be stretched and squashed on any axis.» Raytracing Settings These settings take effect in Raytracing Mode only.286» Material ID: Sets the id of the material.» Illumination:• Upper Hemisphere: Emits light only from the top half of the sphere.• Full Sphere: Emits light from the whole sphere.• Override IBL Sampling Quality: If enabled, the setting overrides the globalIBL Sampling quality for sampling the environment map.
