Ultra-simple one-off tool for importing an .fbx, applying a texture to it, and exporting it as a .gltf.
Based on the three.js GLTF Exporter: https://github.com/mrdoob/three.js/blob/master/examples/misc_exporter_gltf.html
This toy can either be run without building (in Chrome/Edge/Opera since raw three.js examples need Import Maps), or built with:
npm install
npm run build
If building manually, make sure to edit the index .html to point from "./src/main.js" to "./build/main.js".
