Controlling Shadow Resolution Quality in script?

http://answers.unity3d.com/questions/502883/how-can-i-change-the-shadow-resolutions-property-w.html

A bit late, buuuuut: Shadow resolutions are controlled by integers, so if you want to change try this:

 //Very High = 3
 //High = 2
 //Medium = 1
 //Low = 0
 
 QualitySettings.shadowResolution = (ShadowResolution)2;
