Public Attributes#

Type Name Visual Hint Description
long material_sample_count VISUAL_HINT_SAMPLE_PER_PIXEL Set the number of samples to use when computing the shading of a material.
long emission_sample_count VISUAL_HINT_SAMPLE_PER_PIXEL Set the number of samples to use when computing the illumination from a geometric light.
long diffuse_depth VISUAL_HINT_DEFAULT Set the maximum number of times the diffuse channel is sampled along a recursion path.
long specular_reflection_depth VISUAL_HINT_DEFAULT Set the maximum number of times the specular reflection channel is sampled along a recursion path.
long glossy_reflection_depth VISUAL_HINT_DEFAULT Set the maximum number of times the glossy reflection channel is sampled along a recursion path.
long specular_transmission_depth VISUAL_HINT_DEFAULT Set the maximum number of times the specular transmission channel is sampled along a recursion path.
long glossy_transmission_depth VISUAL_HINT_DEFAULT Set the maximum number of times the glossy transmission channel is sampled along a recursion path.
long volume_depth VISUAL_HINT_DEFAULT Set the maximum number of times the volume channel is sampled along a recursion path.
long total_maximum_depth VISUAL_HINT_DEFAULT Set the maximum number of times a material is sampled along a recursion path.
long alpha_depth VISUAL_HINT_DEFAULT Define the recursion limit of the renderer when dealing with transparent objects. When set to Infinite, the renderer stops when the cumulated transparency is under the Alpha Threshold value.
double alpha_threshold VISUAL_HINT_PERCENTAGE Define the alpha value from which a sample is considered transparent.
double diffuse_sampling_multiplier VISUAL_HINT_SCALE Multiply the number of samples that are used to compute the diffuse channel of a material.
double glossy_reflection_sampling_multiplier VISUAL_HINT_SCALE Multiply the number of samples that are used to compute the glossy reflection channel of a material.
double glossy_transmission_sampling_multiplier VISUAL_HINT_SCALE Multiply the number of samples that are used to compute the glossy transmission channel of a material.
double subsurface_sampling_multiplier VISUAL_HINT_SCALE Multiply the number of samples that are used to compute the subsurface channel of a material.
double volume_sampling_multiplier VISUAL_HINT_SCALE Multiply the number of samples that are used to compute the shading of volumes.
double clamping_threshold VISUAL_HINT_DEFAULT Maximum value above which contributions will be clamped in order to attenuate unusually-bright pixels.
double low_light_threshold VISUAL_HINT_DEFAULT Unshadowed illumination below which a light sample is readily assumed to be occluded, hence bypassing the calculation of its actual visibility to a given shading point so as to increase rendering speed.
double russian_roulette VISUAL_HINT_PERCENTAGE Amount of Russian roulette used on the material samples.
double roughness_noise_optimization VISUAL_HINT_PERCENTAGE Noise reduction strategy along rough light path.
double fireflies_filtering VISUAL_HINT_PERCENTAGE Allows to reduce fireflies that could appear in some difficult lighting configurations.
long maximum_splitting_depth VISUAL_HINT_DEFAULT Maximum depth under which we authorize path splitting. Splitting paths reduces noise in specular lobes.
