How to serialize a scene ?

My scene is modified by the code.

I want to serialize my scene and save the JSON file for next time loading.

I use this code :

var jsFile = BABYLON.SceneSerializer.Serialize(myScene);

but it does not work. 

Thanks for your reply and help.

The following is my code, and I make sure 'myScene' is my scene object. 

var saveToJS = function () {
        var jsFile = BABYLON.SceneSerializer.Serialize(myScene);   //alert('ok')
        var js = JSON.stringify(jsFile);
        return js;


I cannot get the results of the serialize function.

The website will crash when call this function:

var jsFile = BABYLON.SceneSerializer.Serialize(myScene);

The alert('ok') function in my code is not called.

Debug result is:

locate:   ambientColor.asArray() in function Serialize()

desc:   JavaScript runtime error: Unable to get property 'asArray' of undefined or null reference

Must I set the ambient color for every object? 

I just added several meshes and  lines.

It can serialize if the scene is empty.

Thanks for your help.

I had this similar error a while back in serializing a scene. I had to modify the babylonjs code to put checks in to not serialize parts of materials that weren't there. However in the latest version of babylon this is fixed. Try using one of these babylonjs files to see if it fixes the problem
