title: How do you name a face in glTF export so that it can be replaced at runtime by THREE.js?
body: <p>I'm able to load a glTF model into THREE.js, but I'm not sure how to proceed with "finding" the right face. Ideally, I could name the face in Blender and after exporting and importing into THREE.js I could do something like <code>mesh.getFaceByName('faceName')</code>. I imagine this would allow me to replace the Material (texture) for that particular face. However, I'm stuck at trying to find the correct face.</p>
