SpotLamp(Lamp)

base classes — bpy_struct, ID, Lamp

class bpy.types.SpotLamp(Lamp)

Directional cone lamp

compression_threshold

Type :CurveMapping, (readonly)

falloff_type

Intensity Decay with distance

Type :enum in [‘CONSTANT’, ‘INVERSE_LINEAR’, ‘INVERSE_SQUARE’, ‘CUSTOM_CURVE’, ‘LINEAR_QUADRATIC_WEIGHTED’], default ‘CONSTANT’

halo_intensity

Brightness of the spotlight’s halo cone

Type :float in [-inf, inf], default 0.0

halo_step

Volumetric halo sampling frequency

Type :int in [0, 12], default 0

linear_attenuation

Linear distance attenuation

Type :float in [0, 1], default 0.0

quadratic_attenuation

Quadratic distance attenuation

Type :float in [0, 1], default 0.0

shadow_adaptive_threshold

Threshold for Adaptive Sampling (Raytraced shadows)

Type :float in [0, 1], default 0.0

shadow_buffer_bias

Shadow buffer sampling bias

Type :float in [0.001, 5], default 0.0

shadow_buffer_clip_end

Shadow map clip end beyond which objects will not generate shadows

Type :float in [0, 9999], default 0.0

shadow_buffer_clip_start

Shadow map clip start: objects closer will not generate shadows

Type :float in [0, 9999], default 0.0

shadow_buffer_samples

Number of shadow buffer samples

Type :int in [1, 16], default 0

shadow_buffer_size

Resolution of the shadow buffer, higher values give crisper shadows but use more memory

Type :int in [512, 10240], default 0

shadow_buffer_soft

Size of shadow buffer sampling area

Type :float in [0, 100], default 0.0

shadow_buffer_type

Type of shadow buffer

• REGULAR Classical, Classic shadow buffer.
• HALFWAY Classic-Halfway, Regular buffer, averaging the closest and 2nd closest Z value to reducing bias artifacts.
• IRREGULAR Irregular, Irregular buffer produces sharp shadow always, but it doesn’t show up for raytracing.
• DEEP Deep, Deep shadow buffer supports transparency and better filtering, at the cost of more memory usage and processing time.

Type :enum in [‘REGULAR’, ‘HALFWAY’, ‘IRREGULAR’, ‘DEEP’], default ‘REGULAR’

shadow_color

Color of shadows cast by the lamp

Type :float array of 3 items in [-inf, inf], default (0.0, 0.0, 0.0)

shadow_filter_type

Type of shadow filter (Buffer Shadows)

• BOX Box, Apply the Box filter to shadow buffer samples.
• TENT Tent, Apply the Tent Filter to shadow buffer samples.
• GAUSS Gauss, Apply the Gauss filter to shadow buffer samples.

Type :enum in [‘BOX’, ‘TENT’, ‘GAUSS’], default ‘BOX’

shadow_method

Method to compute lamp shadow with

• NOSHADOW No Shadow.
• BUFFER_SHADOW Buffer Shadow, Lets spotlight produce shadows using shadow buffer.
• RAY_SHADOW Ray Shadow, Use ray tracing for shadow.

Type :enum in [‘NOSHADOW’, ‘BUFFER_SHADOW’, ‘RAY_SHADOW’], default ‘NOSHADOW’

shadow_ray_sample_method

Method for generating shadow samples: Adaptive QMC is fastest, Constant QMC is less noisy but slower

Type :enum in [‘ADAPTIVE_QMC’, ‘CONSTANT_QMC’], default ‘ADAPTIVE_QMC’

shadow_ray_samples

Amount of samples taken extra (samples x samples)

Type :int in [1, 64], default 0

shadow_sample_buffers

Number of shadow buffers to render for better AA, this increases memory usage

• BUFFERS_1 1, Only one buffer rendered.
• BUFFERS_4 4, Renders 4 buffers for better AA, this quadruples memory usage.
• BUFFERS_9 9, Renders 9 buffers for better AA, this uses nine times more memory.

Type :enum in [‘BUFFERS_1’, ‘BUFFERS_4’, ‘BUFFERS_9’], default ‘BUFFERS_1’

shadow_soft_size

Light size for ray shadow sampling (Raytraced shadows)

Type :float in [-inf, inf], default 0.0

show_cone

Draw transparent cone in 3D view to visualize which objects are contained in it

Type :boolean, default False

spot_blend

The softness of the spotlight edge

Type :float in [0, 1], default 0.0

spot_size

Angle of the spotlight beam in degrees

Type :float in [0.0174533, 3.14159], default 0.0

use_auto_clip_end

Automatic calculation of clipping-end, based on visible vertices

Type :boolean, default False

use_auto_clip_start

Automatic calculation of clipping-start, based on visible vertices

Type :boolean, default False

use_halo

Renders spotlight with a volumetric halo

Type :boolean, default False

use_only_shadow

Causes light to cast shadows only without illuminating objects

Type :boolean, default False

use_shadow_layer

Causes only objects on the same layer to cast shadows

Type :boolean, default False

use_sphere

Sets light intensity to zero beyond lamp distance

Type :boolean, default False

use_square

Casts a square spot light shape

Type :boolean, default False
