It’s honestly a pile of shit when it comes to Babylonjs (mainly). It is just guessing the solution by combining code fragments from various sources and doesn’t have a clue about how things really works generally in 3D, nor in Babylon.js. As @arcman7 said it spills out code with non-existing classes, functions, etc. I event saw threejs classes mixed with Babylon’s ones. Lol.
