- `options` (`object`, optional, default `{}`): Object for passing optional arguments.
    - `options.maxTextureSize` (`number`, optional): Maximum texture size. Texture is resized if over the size.
    - `options.stripUnusedAttributes` (`boolean`, optional): If true, removes unused vertex attributes:

      - Texture coordinates not referenced by materials
      - Vertex colors if not used by materials
      - Tangents if no normal maps are used

      Defaults to false.

**Returns** `Promise<ArrayBuffer>`: - The GLB file content.
