4.14 Render SettingsActivating clamping and reducing the value reduces the maximum resultingimage color range.» Pixel Filter A pixel filter weights the image samples taken per pixel and thereforecontrols the antialiasing quality of the rendering. High image filter sizes mayresult in blurry image results.» Filter: VRED offers seven filter-algorithms for sampling: Box, Triangle, Gaussian,Mitchell Netravali, Lanczos, BSpline and Catmull Rom.» Size: The pixel filter size defines the number of neighboring pixels in width andheight taken into account for filtering.» Features» Optimize for Many Light Sources: Enables the optimization for many lightsources when rendering an image.» Sim2 HDR» Luminance Mapping: Sets the luminance mapping for the Sim2HDR display, ifphotometric parameters are enabled. A value of 1 maps a luminance value of1 cd/m² in the rendering to a value of 1 cd/m² on the Sim2HDR display.4.14.3 Raytracing Quality» Illumination Mode Sets the default lighting mode for materials for interactive andstill frame antialiasing.» Precomputed Illumination: The Precomputed Illumination mode is comparableto VRED OpenGL rendering mode. It uses precomputed ambient occlusionand indirect illumination for rendering and calculates specular reflections andrefractions and correct shadows from light sources.» Precomputed + Shadows: The Precomputed + Shadows Mode uses precomputedimage based lighting and indirect illumination but doesn’t use precom-69
