i've been trying to export a gltf file to three js from blender I have used this tutorial and realised that it may be outdated since the gltf extension they're using is archived and it doesn't appear in the group menu in the uv node editor. How do I export a 3d gltf file suitable for three.js in 2.81 version of blender. There seems to be no tutorial on this. This is pretty confusing since I have never used blender before only maya.
That last link (to the official blender addon docs) is the right workflow, if you already know the basics of creating materials in Blender. If not, I would start with a tutorial on Blender's Principled BSDF, like this one. If you follow the guidelines in the addon docs, a Principled BSDF material will export to glTF correctly.
