Help on Model Materials Three.js

Hi, I am new to Three.js and Verge3d. I have an issue with my glb.file in which my materials that I put on my object (Blinn and Lambert) are not appearing on Three.js. I tried to test it out on the gLTF viewer and got this back. Does anyone know how this is fixable? I am using Maya with the Verge3D plugin to get the file exported.
