2018.1 HDRP shadows and quality settings

So, I seem to be missing something with the 2018.1.0f2 High Definition Render Pipeline. The example workshop scene that loads with it looks great, but I need to know how to get that level of image quality for a large scale scene (highway interchange), especially when it comes to shadows and lighting. When I pull the view back from the scene assets, the shadow quality cuts off quickly and dramatically.

This is for an arch viz animation, so I am not concerned about realtime performance, just a high quality image. Any guidance?

 

I know it's an old thread but it seems that there's no answer to it on google yet. So, studying the 'Book of the Dead' demo scene I found a way to tweak the shadow render. On your 'Hierarchy' click on 'Volume Settings'. Then open the 'HD Shadow Settings' menu and use that options to configure the shadow draw distance. I'm using on my scene at the moment:

Max Distance : 150
Cascade Count: 4
Split 1: 0,144
Split 2: 0,267
Split 3: 0,372

I don't know how much this hits the performance but I didn't noticed any diference.
