I cannot for the life of me figure out why my Anvil model from the famous Guru Blender series tutorial will not export to a glb file for use with WebGL. Since I made it in Blender 2.79b, I have been opening it up in Blender 2.8 and have tried exporting as a glb, gltf, and gltf with separate files.
None of them show all the textures, normal maps, and material design when using glTF Viewer online; the closest I have come is using the GLB packer, but it turns out unlike the Blender file render at all. I have had errors saying a node was empty, which I have no idea where that's at, and I also have had errors saying the images are not a power of 2. When resizing the images even to powers of 2, still doesn't work. I'm completely lost.
I've attached the original blender files that I created in a download link to pcloud, as well as the way the blender render looks and needs to look as a glb. Please help in showing me how to export everything so all the materials and textures are in a glb format and available for viewing on WebGL!!
