Trying to get something like this working:

saveTileMaps(){
		let maps = []
		for(var i=0; i<this.layers.length; i++){
			maps.push(this.layers[i]._texture._bufferView)
		}
		BABYLON.Tools.Download(maps, this.name+'.tilemaps')
	}

asking for a friend.

Nevermind… thought about it really quick.

let blob = new Blob(maps, {type: "octet/stream"})	
BABYLON.Tools.Download(blob, this.name+'.tilemaps')
