4.14 Render Settings» Monitor Luminance (cd/m²): This parameter is used to set up the luminancevalue of the preferred display. When using photometric parameters, the actualmonitor luminance is necessary to reproduce the rendering results with realisticphotometric values on the display device.» Enable Photometric Parameters: Use photometric parameters as preferred mode.The setting does not apply to the current scene, only to newly generatedscenes. For a description of photometric consistent rendering, please read thechapter on Render Settings.» 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 precomputedAmbient Occlusion values. Instead it calculates shadows based on theactive environment.» Precomputed + IBL: The Precomputed + IBL Mode uses precomputed indirectillumination and samples the environment. It replaces the old Fast Global Illuminationmode.79
