Blender Export glTF with Texture Setup

This is the source file in my YouTube tutorial https://youtu.be/O-pyWY7rFSo
Inside the blend file, you'll find the node setup I showed in the video, which you can use as a reference when you're exporting your own model. Please note that the helmet model is CC license but with no commercial use allowed, this is only to demonstrate my node setup and not the model itself.
