Babylon JS - How to optimized loading by using cache

[Amethyst17]

So I have 2 files:

1. shirt.obj

2. shirt.mtl

 

I want to load this via babylon.js:

BABYLON.SceneLoader.Load(folder, fileName, $scope.engine, function (loadedScene) {...}

What should I do to optimized the file loader?

I have read the cache optimization from the babylon.js documentation, but none are working.

Babylon Caching Docs

 

I keep getting the model file from cache, I already put the updated model into the resources folder. How to load the new model file?

 

What should I name my manifest file? I tried shirt.obj.manifest and shirt.babylon.manifest, both of them did not work.

And what code should I insert in my script?
