I saw this tutorial: https://www.youtube.com/watch?v=Tovu1A0LxeQ
And now I'm trying to export my model into obj file with textures. However, seems this is not possible to achieve with the cycles render (from what I read).
So, is there a way to do the same process using the internal render, so that I can have my obj/mtl file referencing the uv layout png file?
The final goal is to publish my model into Facebook, which needs glb file. So I was trying to get first the correct obj file and then convert it to the glb file.
