Hi,   I got a small problem with conversion from rotation vector to quaternion and back to rotation vector. I searched a bit and found this - http://www.html5gamedevs.com/topic/3159-quaternionrotationyawpitchroll-parameters-and-toeulerangles-result-should-be-the-same/page-2 so I ran the very simple test that was suggested there: var e = new BABYLON.Vector3(0.1, 0.2, 0.3);var q = BABYLON.Quaternion.RotationYawPitchRoll(e.y, e.x, e.z); console.log(e); console.log(q.toEulerAngles())
