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)

is_grease_pencil

True if this material has grease pencil data

Line color used for Freestyle line rendering

Type

float array of 4 items in [0, inf], default (0.0, 0.0, 0.0, 0.0)

line_priority

The line color of a higher priority is used at material boundaries

Type

int in [0, 32767], default 0

metallic

Amount of mirror reflection for raytrace

Type

float in [0, 1], default 0.0

node_tree

Node tree for node based materials

Type

NodeTree, (readonly)

paint_active_slot

Index of active texture paint slot

Type

int in [0, 32767], default 0

paint_clone_slot

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

use_backface_culling

Use back face culling to hide the back side of faces

Type

boolean, default False

use_nodes
