If you want the sun to project volumetric beams, make sure to select the sunlight and turn the 'volumetric light' on. Two notes about doing this : - When the sunlight is volumetric, the light intensity is controlled by the 'intensity' slider in the volumetric panel. - It is best to not mix too many volumetric things together. Do volumetric atmosphere OR sun OR materials... separately. Now... you will have a better control of your scene if, instead of making the sunlight volumetric, you add a volumetric point light to your scene instead.
