An extension to easily create or update any NodeMaterial.
Call the method Show of the BABYLON.NoteMaterial class:
BABYLON.NoteMaterial.Show({hostElement: document.getElementById("host")});
This method will retrieve dynamically the library nodeEditor.js, download it and add
it to the html page.
If you don't have access to internet, the node editor should be imported manually in your HTML page :
<script src="babylon.nodeEditor.js" />
