This is what it looks like no matter the settings I use when I try to use shadows in Unity. Changing the Bias or the Normal Bias does effect the shadows, but I cannot get the shadows to be smooth with any settings. Making the model bigger does fix this, but I would optimally not scale the model up, as it is already at 10.
Use hard shadow with very high shadow resolution. This will effect on editor as well as build. Change quality settings levels for your intended platform. In shadow section hard shadow only and very high shadow resolution. May also increase anti aliasing in rendering section. These will effect on build quality.
So it seems like while changing the quality settings did increase the quality of the shadows it did not remove the artifacts, but when I was int he QualitySettings menu, I saw some settings that I had seen in other forums. Changing the shadow distance to a lower value increased the quality of the shadows and removed the artifacts. This also allows the use of soft shadows, but the bias then needs to be increased slightly to .005.
