Option to inject self-loaded `MeshoptDecoder`

Could we please have an option to inject a self-loaded MeshoptDecoder?

Although we can do something like

BABYLON.MeshoptCompression.Configuration = {
    decoder: {
        url: "<url to the meshopt decoder library>"
    }
};

this only works in the browser (but not Node, since BABYLON.Tools.LoadBabylonScriptAsync() doesn’t work in Node)

I’d like to be able to self-load meshopt_decoder.js and have Babylon.js detect that MeshoptDecoder is already loaded so that it doesn’t try to load it again

Thank you for your help :smile:

As a quick workaround, this should work, too:

//  ↓↓↓  see also e.g. https://github.com/JamesJansson/importScripts/blob/master/importscripts.js
global.importScripts = function(url) { console.log("URL", url); }

const scriptUrl = "www.babylonjs.com";
const onSuccess = ()=>{ console.log("Success"); };
const onError = (msg)=>{ throw new Error(msg); };

//https://github.com/BabylonJS/Babylon.js/blob/master/packages/dev/core/src/Misc/tools.ts#L583
if (typeof importScripts === "function") {
	try {
		importScripts(scriptUrl);
		if (onSuccess) {
			onSuccess();
		}
	} catch (e) {
		onError?.(`Unable to load script '${scriptUrl}' in worker`, e);
	}
}

When running in Node.js, it prints the url and “success”.

Thank you so much, @Joe_Kerr, your approach works great! It inspired the workaround I ended up going with for now (overriding LoadBabylonScriptAsync() with an empty function):

BABYLON.Tools.LoadBabylonScriptAsync = async (url: string): Promise<void> => {};
