GltfMaterial

glTF material — PBR base color factor + optional base color texture. Phase 2 ignores metallic/roughness/normal/emissive — they're recorded by the reader as defaults for future expansion without consumer churn.

Properties

alphaBlend

val alphaBlend: Boolean

True when the material uses alpha blending (alphaMode = "BLEND").

alphaCutoff

val alphaCutoff: Float

Alpha cutoff used when alphaMask is true. Default 0.5 per spec.

alphaMask

val alphaMask: Boolean

True when the material uses alpha masking (alphaMode = "MASK").

baseColorFactor

val baseColorFactor: FloatArray

PBR base color (linear sRGB premultiplied with factor; values are in 0, 1).

baseColorTextureImageIndex

val baseColorTextureImageIndex: Int

Index into GltfModel.images for the base color texture, or -1 when none.

baseColorTextureTexCoordSet

val baseColorTextureTexCoordSet: Int

Texcoord set used by the base color texture. Almost always 0; tracked for completeness.

doubleSided

val doubleSided: Boolean

True when the material disables back-face culling (doubleSided in glTF).
