base classes — bpy_struct, ID, Light

class bpy.types.SunLight(Light)#

Constant direction parallel ray Light

angle#

Angular diameter of the Sun as seen from the Earth

Type:

float in [0, 3.14159], default 0.00918043

contact_shadow_bias#

Bias to avoid self shadowing

Type:

float in [0.001, 9999], default 0.03

contact_shadow_distance#

World space distance in which to search for screen space occluder

Type:

float in [0, 9999], default 0.2

contact_shadow_thickness#

Pixel thickness used to detect occlusion

Type:

float in [0, 9999], default 0.2

energy#

Sunlight strength in watts per meter squared (W/m²)

Type:

float in [-inf, inf], default 10.0

shadow_buffer_bias#

Bias for reducing self shadowing

Type:

float in [0, inf], default 1.0

shadow_buffer_clip_start#

Shadow map clip start, below which objects will not generate shadows

Type:

float in [1e-06, inf], default 0.05

shadow_cascade_count#

Number of texture used by the cascaded shadow map

Type:

int in [1, 4], default 4

shadow_cascade_exponent#

Higher value increase resolution towards the viewpoint

Type:

float in [0, 1], default 0.8

shadow_cascade_fade#

How smooth is the transition between each cascade

Type:

float in [0, 1], default 0.1

shadow_cascade_max_distance#

End distance of the cascaded shadow map (only in perspective view)

Type:

float in [0, inf], default 200.0

shadow_color#

Color of shadows cast by the light

Type:

mathutils.Color of 3 items in [0, inf], default (0.0, 0.0, 0.0)

shadow_filter_radius#

Blur shadow aliasing using Percentage Closer Filtering

Type:

float in [0, inf], default 1.0

shadow_jitter_overblur#

Apply shadow tracing to each jittered sample to reduce under-sampling artifacts

Type:

float in [0, 100], default 10.0

shadow_maximum_resolution#

Minimum size of a shadow map pixel. Higher values use less memory at the cost of shadow quality

Type:

float in [0, inf], default 0.001

shadow_soft_size#

Light size for ray shadow sampling (Raytraced shadows)

Type:

float in [0, inf], default 0.0

use_contact_shadow#

Use screen space ray-tracing to have correct shadowing near occluder, or for small features that does not appear in shadow maps

Type:

boolean, default False

use_shadow_jitter#

Enable jittered soft shadows to increase shadow precision (disabled in viewport unless enabled in the render settings). Has a high performance impact

Type:

boolean, default False
