Currently in beta but set to launch officially later this year, After Effects will soon allow you to render and manipulate 3D objects directly in the software, removing the requirement to export huge TIFF sequences from Cinema4D. Unfortunately with my Cinema4D student license nearing its end, I needed to export my models to the desired GLB format pronto. Wanting to ensure this procedure had been done correctly, but with the AE feature still in development, Babylon.js stepped up to be my saving grace with its wonderful Sandbox.
