Not a fan of The Blob-y shadows artstyle for characters. Been trying to change it. apparently it's tied to the game's shadow distance scale and resolution. The max possible resolution for shadow is 8192 and if you go above that the game will crash. In order to make character shadows less Blob-y had to lower the shadow distance scale and had to increase the shadow to max possible resolution. But this would cause environmental shadows to pop in and out. So the best I could do was to strike a balance between the Blob-y ness of the character shadows and the environmental shadows distance scale to make it less pop-y:
[SystemSettings]
r.ShadowQuality=5
r.Shadow.DistanceScale=1.4 ; game default = 1
r.Shadow.MaxCSMResolution=8192
r.Shadow.MaxResolution=8192
