public abstract class MaterialBase : NamedObject

Fields

alphaCutoff

Specifies the cutoff threshold when in MASK mode. If the alpha value is greater than or equal to this value then it is rendered as fully opaque, otherwise, it is rendered as fully transparent. This value is ignored for other modes.

Declaration

public float alphaCutoff

Field Value

Type	Description
float

alphaMode

The material's alpha rendering mode enumeration specifying the interpretation of the alpha value of the main factor and texture. In OPAQUE mode, the alpha value is ignored and the rendered output is fully opaque. In MASK mode, the rendered output is either fully opaque or fully transparent depending on the alpha value and the specified alpha cutoff value. In BLEND mode, the alpha value is used to composite the source and destination areas. The rendered output is combined with the background using the normal painting operation (i.e. the Porter and Duff over operator).

Declaration

[Obsolete("Use GetAlphaMode and SetAlphaMode for access.")]
public string alphaMode

Field Value

Type	Description
string

doubleSided

Specifies whether the material is double sided. When this value is false, back-face culling is enabled. When this value is true, back-face culling is disabled and double sided lighting is enabled. The back-face must have its normals reversed before the lighting equation is evaluated.

Declaration

public bool doubleSided

Field Value

Type	Description
bool

emissiveFactor

The RGB components of the emissive color of the material. If an emissiveTexture is specified, this value is multiplied with the texel values.

Declaration

[Obsolete("Use Emissive for access.")]
public float[] emissiveFactor

Field Value

Type	Description
float[]

Properties

Emissive

Emissive color of the material.

Declaration

public Color Emissive { get; set; }

Property Value

Type	Description
Color

EmissiveTexture

The emissive map controls the color and intensity of the light being emitted by the material. This texture contains RGB components in sRGB color space. If a fourth component (A) is present, it is ignored.

Declaration

public abstract TextureInfoBase EmissiveTexture { get; }

Property Value

Type	Description
TextureInfoBase

Extensions

Material extensions.

Declaration

public abstract MaterialExtensions Extensions { get; }

Property Value

Type	Description
MaterialExtensions

NormalTexture

A tangent space normal map. Each texel represents the XYZ components of a normal vector in tangent space.

Declaration

public abstract NormalTextureInfoBase NormalTexture { get; }

Property Value

Type	Description
NormalTextureInfoBase

OcclusionTexture

The occlusion map is a greyscale texture, with white indicating areas that should receive full indirect lighting and black indicating no indirect lighting.

Declaration

public abstract OcclusionTextureInfoBase OcclusionTexture { get; }

Property Value

Type	Description
OcclusionTextureInfoBase

PbrMetallicRoughness

A set of parameter values that are used to define the metallic-roughness material model from Physically-Based Rendering (PBR) methodology.

Declaration

public abstract PbrMetallicRoughnessBase PbrMetallicRoughness { get; }

Property Value

Type	Description
PbrMetallicRoughnessBase

RequiresNormals

True if the material requires the mesh to have normals.

Declaration

public bool RequiresNormals { get; }

Property Value

Type	Description
bool

RequiresTangents

True if the material requires the mesh to have tangents.

Declaration

public bool RequiresTangents { get; }

Property Value

Type	Description
bool

Methods

GetAlphaMode()

MaterialBase.AlphaMode typed and cached getter for alphaMode string.

Declaration

public MaterialBase.AlphaMode GetAlphaMode()

Returns

Type	Description
MaterialBase.AlphaMode	Alpha mode if it was retrieved correctly. Opaque otherwise

SetAlphaMode(AlphaMode)

MaterialBase.AlphaMode typed setter for alphaMode string.

Declaration

public void SetAlphaMode(MaterialBase.AlphaMode mode)

Parameters

Type	Name	Description
MaterialBase.AlphaMode	mode	Alpha mode
