Material(ID)

base classes — bpy_struct, ID

class bpy.types.Material(ID)

Material data-block to define the appearance of geometric objects for rendering

alpha_threshold

A pixel is rendered only if its alpha value is above this threshold

Type

float in [0, 1], default 0.5

animation_data

Animation data for this data-block

Type

AnimData, (readonly)

blend_method

Blend Mode for Transparent Faces

  • OPAQUE Opaque, Render surface without transparency.

  • CLIP Alpha Clip, Use the alpha threshold to clip the visibility (binary visibility).

  • HASHED Alpha Hashed, Use noise to dither the binary visibility (works well with multi-samples).

  • BLEND Alpha Blend, Render polygon transparent, depending on alpha channel of the texture.

grease_pencil

Grease pencil color settings for material

Type

MaterialGPencilStyle, (readonly)

metallic

Amount of mirror reflection for raytrace

Index of clone texture paint slot

Type

int in [0, 32767], default 0

pass_index

Index number for the “Material Index” render pass

Type

int in [0, 32767], default 0

preview_render_type

Type of preview render

  • FLAT Flat, Flat XY plane.

  • SPHERE Sphere, Sphere.

  • CUBE Cube, Cube.

  • HAIR Hair, Hair strands.

  • SHADERBALL Shader Ball, Shader ball.

  • CLOTH Cloth, Cloth.

  • FLUID Fluid, Fluid.

Type

enum in [‘FLAT’, ‘SPHERE’, ‘CUBE’, ‘HAIR’, ‘SHADERBALL’, ‘CLOTH’, ‘FLUID’], default ‘SPHERE’

refraction_depth

Approximate the thickness of the object to compute two refraction event (0 is disabled)

Type

float in [0, inf], default 0.0

roughness

Roughness of the material

Type

float in [0, 1], default 0.4

shadow_method

Shadow mapping method

  • NONE None, Material will cast no shadow.

  • OPAQUE Opaque, Material will cast shadows without transparency.

  • CLIP Alpha Clip, Use the alpha threshold to clip the visibility (binary visibility).

  • HASHED Alpha Hashed, Use noise to dither the binary visibility and use filtering to reduce the noise.

Type

enum in [‘NONE’, ‘OPAQUE’, ‘CLIP’, ‘HASHED’], default ‘OPAQUE’

show_transparent_back

Limit transparency to a single layer (avoids transparency sorting problems)

Type

boolean, default False
