This tutorial explains how to edit glTF files using open source software to add material extensions KHR_materials_transmission and KHR_materials_volume to create glass with reflection, refraction, and absorption.
These methods can be repurposed for other material extensions too.
The glTF model used in this tutorial is available in the samples folder.
