Application-Specific data

Optionalname

name?: string

The user-defined name of this object

OptionalpbrMetallicRoughness

pbrMetallicRoughness?: IMaterialPbrMetallicRoughness

A set of parameter values that are used to define the metallic-roughness material model from Physically-Based Rendering (PBR) methodology. When not specified, all the default values of pbrMetallicRoughness apply

OptionalnormalTexture

normalTexture?: IMaterialNormalTextureInfo

The normal map texture

OptionalocclusionTexture

occlusionTexture?: IMaterialOcclusionTextureInfo

The occlusion map texture

OptionalemissiveTexture

emissiveTexture?: ITextureInfo

The emissive map texture

OptionalemissiveFactor

emissiveFactor?: number[]

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

OptionalalphaMode

alphaMode?: MaterialAlphaMode

The alpha rendering mode of the material

OptionalalphaCutoff

alphaCutoff?: number

The alpha cutoff value of the material

OptionaldoubleSided

doubleSided?: boolean

Specifies whether the material is double sided

Optionalextensions

extensions?: GLTFMaterialsExtensions

Dictionary object with material extension-specific objects
