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
Single

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
[SerializeField]
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
Boolean

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 TextureInfo emissiveTexture
Field Value
Type Description
TextureInfo

extensions

Material extensions.

Declaration
public MaterialExtension extensions
Field Value
Type Description
MaterialExtension

normalTexture

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

Declaration
public NormalTextureInfo normalTexture
Field Value
Type Description
NormalTextureInfo

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 OcclusionTextureInfo occlusionTexture
Field Value
Type Description
OcclusionTextureInfo

pbrMetallicRoughness

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

Declaration
public PbrMetallicRoughness pbrMetallicRoughness
Field Value
Type Description
PbrMetallicRoughness

Properties

Emissive

Emissive color of the material.

Declaration
public Color Emissive { get; set; }
Property Value
Type Description
Color

RequiresNormals

True if the material requires the mesh to have normals.

Declaration
public bool RequiresNormals { get; }
Property Value
Type Description
Boolean

RequiresTangents

True if the material requires the mesh to have tangents.

Declaration
public bool RequiresTangents { get; }
Property Value
Type Description
Boolean

Methods

GetAlphaMode()

Material.AlphaMode typed and cached getter for alphaMode string.

Declaration
public Material.AlphaMode GetAlphaMode()
Returns
Type Description
Material.AlphaMode

Alpha mode if it was retrieved correctly. Opaque otherwise

SetAlphaMode(Material.AlphaMode)

Material.AlphaMode typed setter for alphaMode string.

Declaration
public void SetAlphaMode(Material.AlphaMode mode)
Parameters
Type Name Description
Material.AlphaMode mode

Alpha mode
