8.1 Truelight Materials» Saturation: Sets the HDR-Image’s saturation.» Reflected Saturation: Sets the HDR-Image’s saturation when the HDR-Image reflectsin any surface.» Transformation With transformation parameters the source of spherical projectionof the SphereEnvironment Material can be set.» Environment Size: Sets the radius of the SphereEnvironment Material’s projectionsphere. The projection sphere must enclose all objects using a material havingthis SphereEnvironment Material as environment shader assigned. All objectsthat are outside of the projection sphere using a Truelight Material with thisSphereEnvironment Material as input channel, will not be rendered properly.» Center X, Y, Z: 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 SphereEnvironment Material’s orientation.» Scale X, Y, Z: Sets the SphereEnvironment Material’s size. With the scale valuethe image projection can be stretched and squashed on any axis.» Raytracing Settings These settings take effect in Raytracing Mode only.» 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.· Interactive Quality: Sets the IBL sampling quality during interactive rendering.231
