I am unable to modify (increase) the idleRotationSpeed of my ArcRotateCamera. I tried adjusting the values of speed.idleRotationSpeed but to no avail; the arc rotation camera always circles the object at the same rate. Here is a code snippet:
var camera = new BABYLON.ArcRotateCamera("arcCam",
10,1,30,
BABYLON.Vector3.Zero(),scene);
camera.attachControl(canvas,true);
camera.upperBetaLimit = Math.PI / 2;
camera.lowerRadiusLimit = 4;
var speed = new BABYLON.AutoRotationBehavior("camera",scene);
speed.idleRotationSpeed = 0.01;
speed.parent = camera;
camera.useAutoRotationBehavior = true;
