Hey there, I started doing WebGL-stuff yesterday and did the PlayPen-Tutorials till "Animations". For a scene I created (http://perditio.com/babylontest/index.html) I want to animate a sunrise using a Hemisoherical Light and its Vector3-positions. The Problem: It simply doesn't work. The light does not move / travel to the location. You can find the code here: http://www.babylonjs-playground.com/#11ZVTO It would be great if anyone can help. Thanks!
