MaterialVolume(bpy_struct)¶
base class — bpy_struct
- class bpy.types.MaterialVolume(bpy_struct)¶
Volume rendering settings for a Material datablock
- asymmetry¶
Back scattering (-1.0) to Forward scattering (1.0) and the range in between
Type : float in [-1, 1], default 0.0
- cache_resolution¶
Resolution of the voxel grid, low resolutions are faster, high resolutions use more memory
Type : int in [1, 1024], default 0
- density¶
The base density of the volume
Type : float in [0, 1], default 0.0
- density_scale¶
Multiplier for the material’s density
Type : float in [0, inf], default 0.0
- depth_threshold¶
Stop ray marching early if transmission drops below this luminance - higher values give speedups in dense volumes at the expense of accuracy
Type : float in [0, 1], default 0.0
- emission¶
Amount of light that gets emitted by the volume
Type : float in [0, inf], default 0.0
- emission_color¶
Color of emitted light
Type : float array of 3 items in [-inf, inf], default (0.0, 0.0, 0.0)
- light_method¶
Method of shading, attenuating, and scattering light through the volume
Type : enum in [‘SHADELESS’, ‘SHADOWED’, ‘SHADED’, ‘MULTIPLE_SCATTERING’, ‘SHADED_PLUS_MULTIPLE_SCATTERING’], default ‘SHADELESS’
- ms_diffusion¶
Diffusion factor, the strength of the blurring effect
Type : float in [0, inf], default 0.0
- ms_intensity¶
Multiplier for multiple scattered light energy
Type : float in [0, inf], default 0.0
- ms_spread¶
Proportional distance over which the light is diffused
Type : float in [0, inf], default 0.0
- reflection¶
Multiplier to make out-scattered light brighter or darker (non-physically correct)
Type : float in [0, inf], default 0.0
- reflection_color¶
Color of light scattered out of the volume (does not affect transmission)
Type : float array of 3 items in [-inf, inf], default (0.0, 0.0, 0.0)
- scattering¶
Amount of light that gets scattered out by the volume - the more out-scattering, the shallower the light will penetrate
Type : float in [0, inf], default 0.0
- step_method¶
Method of calculating the steps through the volume
Type : enum in [‘RANDOMIZED’, ‘CONSTANT’], default ‘RANDOMIZED’
- step_size¶
Distance between subsequent volume depth samples
Type : float in [0, inf], default 0.0
- transmission_color¶
Result color of the volume, after other light has been scattered/absorbed
Type : float array of 3 items in [-inf, inf], default (0.0, 0.0, 0.0)
- use_external_shadows¶
Receive shadows from sources outside the volume (temporary)
Type : boolean, default False
- use_light_cache¶
Pre-calculate the shading information into a voxel grid, speeds up shading at slightly less accuracy
Type : boolean, default False
