GLTF/obj structure and modifying object loaded

@labris My apology!! I was trying to convert .obj & .mtl to .bin & .glTF and for some reason, it kept failing and missing .bin file so I could not load an object then it messed up my mind @_@

I was looking into 3D model importing and found out that Three.js recommends glTF as the optimal format, but also supports .fbx, .obj, .collada, etc. However, .fbx is not supported in Babylon.js

I took a look at this forum question/answer and realized why it would be inefficient to load an .fbx type model.

I am betting on glTF, but If you were to pick the best format for a 3D model, what would it be?
