Hey guys how is life?

Well i am new with maya, and have been struglin for 2 weeks now. I have creatid an ocean with realistic looking waves. That all went fine.
But know i want to make a sun in the sky with glow (but i dont want the lightning of the sun to effect the ocean).

I got the light in the scene, and adjusted the atributes. The glow,fog,halow,star, lens flare and stuf. Until i got a nice lookin sun in the preview. But when i render i get a little dot of a light, with a black looking star and without glow and everything else. and if i scale it i just get a white big round looking spot, without everything.

Can somebody pleas help on how to make a sun with nice glow. Or forward me to a tutorial on how to do it.Or who can tell me the atributes.

Thanks
