*If you put a tall cube (rectangular) in front of a low volumetric sun does it kick out nice shadows above and below the object on the PC?* Well, yes and no. *grin* They don't necessarily show up "automatically." It's a matter of balance between setting adjustments and the relationship of sun-to-camera angles. Make sure you have a volumetric atmosphere and the sun is set to volumetric. Open the volumetric sun settings and enable smoke/dust, and turn up the intensity. Depending on the effect you want to achieve, you might turn the intensity *way* up, like 300 or 400%.
