Hey, I got an issue with version 2-2012. As soon I make an example map with a random terrain and a filled skyspehere, nothing's wrong yet. But, as soon I add a dominant directional light, several lines of the skysphere as well as the terrain are suddenly blackening out. I'll try to upload an image of it soon so you can see what's wrong. With my previous version, 11-2011, it occured as well.
