attributes: readonly ShaderAttributeName[]
backFaceCulling: boolean
blend?: GPUBlendState

Explicit blend-state override (see ShaderMaterialOptions.blend).

blendMode: "additive" | "alpha"
color: Color4
defines: readonly ShaderDefine[]
depthBias: number
depthBiasSlopeScale: number
depthCompare: GPUCompareFunction
depthOnlyFragment: boolean
depthWrite: boolean
fragmentSource: WgslSource
metadata?: LiteMetadata

User metadata. glTF loads populate metadata.gltf.extras when source extras exist.

name?: string

Optional human-readable name. Populated by loaders from the source asset (e.g. the glTF material name) so callers can look a material up by name.

needAlphaBlending: boolean
needAlphaTesting: boolean
samplerDecls: readonly ShaderSamplerDecl[]
stencil?: StencilState

Optional stencil-test state baked into the main-pass pipeline (mask write / discard). Set after creation (mat.stencil = { ... }) and call enableMaterialStencil() before registerScene. Default none. See StencilState.

storageBufferDecls: readonly ShaderStorageBufferDecl[]
transmissive: boolean

True for transmissive/refractive surfaces (see ShaderMaterialOptions.transmissive).

uniformDecls: readonly ShaderUniformDecl[]
useThinInstanceColors: boolean
useThinInstances: boolean
useVertexAlpha: boolean
useVertexColor: boolean
vertexSource: WgslSource
