KHRMaterialsSpecular

KHR_materials_specular adjusts the strength of the specular reflection in the dielectric BRDF.

KHRMaterialsSpecular is a better alternative to the older KHR_materials_pbrSpecularGlossiness extension, and provides specular information while remaining within a metal/rough PBR workflow. A value of zero disables the specular reflection, resulting in a pure diffuse material.

Properties:

• Specular

Example

The KHRMaterialsSpecular class provides a single ExtensionProperty type, Specular, which may be attached to any Material instance. For example:

import { KHRMaterialsSpecular, Specular } from '@gltf-transform/extensions';

// Create an Extension attached to the Document.
const specularExtension = document.createExtension(KHRMaterialsSpecular);

// Create a Specular property.
const specular = specularExtension.createSpecular()
    .setSpecularFactor(1.0);

// Attach the property to a Material.
material.setExtension('KHR_materials_specular', specular);
