3D rendering

we are implementing 3D glassess try on feature with [login to view URL] (some what similar to lenskart ) in our website .we are using blender to generate mesh file for our glasses . we're exporting glasses from blender to JSON format and render it in [login to view URL] at website. what problem we are facing right now is :when we export our JSON file from blender . there is no any material , texture or light in that file .. so at the time of rendering it is just black shape of spectacles. we want to achieve similar functionality like lenskart . So we don't know the reason behind material less JSON file . Is there any configuration we have to do in our blender ? Should we have to add light , texture at [login to view URL] (Web) side ? How to export mesh file with material , texture and light ?
