+ * 2. give it a position in the scene
+ * 3. call {@link LightProbeFactory#makeProbe(com.jme3.environment.EnvironmentCamera, com.jme3.scene.Node)}

+ * 
+ * Optionally for step 3 call {@link LightProbeFactory#makeProbe(com.jme3.environment.EnvironmentCamera, com.jme3.scene.Node, com.jme3.environment.generation.JobProgressListener) }
+ * with a {@link JobProgressListener} to be notified of the progress of the generation process.
+ * 
+ * The generation will be split in several threads for faster generation. 
+ * 
+ * This class is entirely thread safe and can be called from any thread. 
+ * 
+ * Note that in case you are using a {@link JobProgressListener} all the its 
+ * method will be called inside and app.enqueu callable.
+ * This means that it's completely safe to modify the scenegraph within the
