Example

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

import { KHRMaterialsSheen, Sheen } from '@gltf-transform/extensions';

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

// Create a Sheen property.
const sheen = sheenExtension.createSheen()
    .setSheenColorFactor([1.0, 1.0, 1.0]);

// Attach the property to a Material.
material.setExtension('KHR_materials_sheen', sheen);

Methods

  • dispose(): void
  • isRequired(): boolean

  • Indicates to the client whether it is OK to load the asset when this extension is not recognized. Optional extensions are generally preferred, if there is not a good reason to require a client to completely fail when an extension isn't known.

  • listProperties(): ExtensionProperty[]

  • Indicates to the client whether it is OK to load the asset when this extension is not recognized. Optional extensions are generally preferred, if there is not a good reason to require a client to completely fail when an extension isn't known.
