Description#

A physical light that is sending the same illumination in all directions from its center.

Public Attributes#

Type Name Visual Hint Description
double radius VISUAL_HINT_DISTANCE Set the radius of the light source. If it is 0 the light is consider as a point light
long direction VISUAL_HINT_DEFAULT Set the direction of the illumination.
bool enable_ies VISUAL_HINT_DEFAULT Angular emission type used for this light.
string ies_filename VISUAL_HINT_FILENAME_OPEN IES file name.
double mix VISUAL_HINT_DEFAULT Mixes in the amount of IES output you want.
long interpolation_type VISUAL_HINT_DEFAULT Type of angular interpolation used.
double cone_angle_angular VISUAL_HINT_ANGLE The full aperture of the Spot.
double softness VISUAL_HINT_PERCENTAGE Multiplier for the angular penumbra of the Spot.
double softness_exponent VISUAL_HINT_DEFAULT Exponent used for the softness of the Spot.
double spot_scale VISUAL_HINT_SCALE Scale of the spot angle.
double light_power VISUAL_HINT_DEFAULT Power, in units homogeneous to Watts.
long volume_sampler VISUAL_HINT_DEFAULT Specifies the accuracy of the importance sampling used to place volume samples. Basic mode is faster and distributes samples using a simple distribution. Advanced mode samples the light much more precisely and is good for lights with narrow beams such a spot and IES lights. It may be slightly slower for large numbers of lights.

Inherited Public Attributes#

Type Name Visual Hint Description
double[3] translate VISUAL_HINT_DISTANCE Set the XYZ position of the item relative to its parent item.
double[3] rotate VISUAL_HINT_ANGLE Set the XYZ rotation of the item relative to its parent item.

double[3] shear VISUAL_HINT_SCALE Set the XYZ shear of the item relative to its parent item.

long sample_count VISUAL_HINT_SAMPLE_PER_PIXEL Set the number of samples per pixel to use to evaluate the light.
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 transmission_weight VISUAL_HINT_PERCENTAGE Multiply the light contribution on the transmission lobes.

double[3] shadow_color VISUAL_HINT_COLOR Shadow color of the light.
reference (Group) shadow_group VISUAL_HINT_GROUP Group of objects that have to be considered when casting a ray for shadows or global illumination. If not set, the corresponding groups in the layer are taken by default.
long diffuse_max_depth VISUAL_HINT_DEFAULT Set whether the light is hidden from the diffuse reflections and transmissions after a number of diffuse bounces.
long reflections_max_depth VISUAL_HINT_DEFAULT Set whether the light is hidden from the specular and glossy reflections after a number of reflections bounces.
long transmissions_max_depth VISUAL_HINT_DEFAULT Set whether the light is hidden from the specular and glossy transmissions after a number of transmissions bounces.

long total_max_depth VISUAL_HINT_DEFAULT Set whether the light is hidden from reflections and transmissions after a total number of indirect bounces.
long attenuation_mode VISUAL_HINT_DEFAULT Enable the light intensity attenuation that multiplies the falloff to get the final light intensity decay.
double attenuation_near_start VISUAL_HINT_DISTANCE Set the distance from the light at which near attenuation starts. Any object whose distance is shorter than the specified value will not receive any illumination from the light.
double attenuation_near_end VISUAL_HINT_DISTANCE Set the distance from the light at which near attenuation ends. Any object whose distance is longer than the specified value will receive the full illumination from the light.
double attenuation_far_start VISUAL_HINT_DISTANCE Set the distance from the light at which far attenuation starts. Any object whose distance is shorter than the specified value will receive the full illumination from the light.
double attenuation_far_end VISUAL_HINT_DISTANCE Set the distance from the light at which far attenuation ends. Any object whose distance is longer than the specified value will not receive any illumination from the light.
curve attenuation_curve VISUAL_HINT_DEFAULT Multiplies the light intensity profile. The specified curve uses the distance of the object to the light as input.
string light_path_expression_label VISUAL_HINT_DEFAULT Set the light label in light path expressions.
bool aov_exclusive VISUAL_HINT_DEFAULT If turned on, this light will not contribute to the beauty but only to Light Path Expression AOVs, and under the 'X' symbol instead of the usual 'L'. When enabled, this light will not contribute to the unoccluded results ('U' symbol in LPEs) either and will not be seen by the camera.
