This is using Eevee in Rendered mode. Whenever I re-position the sun light it can sometimes create this jagged and spikey artefact. Is there any way around this? Something that can smooth it perhaps?
Is it set for Soft Shadows under the Shadow Tab?
It wasn’t, no. That’s softened them up a bit at least. Thanks. 
Though I’m still getting jaggy shadows.
EDIT: Hmm. It appears to cause a lot of flickering though. :-\
