hello!

i got a problem with controlP5 and the lightning of the canvas.
right now, i'm using a very specific way of illuminating the scene, which is

Code:

	private void initializeLight() {
		ambientLight(190, 190, 190, 
				     width/2, height/2, -500);
		pointLight(255, 255, 255, 
				   width/2, height/2, 5);
		spotLight(255, 255, 255, 
				  width, height, 100, 
				  -1, 0, -1, 80, 20);
	} 

every time i activate my gui using the controlP5 the whole lightning gets mixed up. does anybody have any hints?

even if I only use

Code:

controlP5 = new ControlP5(this.papplet); 

and the draw it with

Code:

controlP5.draw(); 

it messes up the scene. any hints and tricks are highly appreciated. thanks!
