Not sure if this is a bug or something I’m getting wrong…
I spent a few hours trying to work out why shadows weren’t showing on smaller objects. In the project settings under rendering I tried changing the ‘Min screen radius for cascaded shadow maps’ (it seemed to be the most obvious culprit) with no impact.
I came across this post: Shadows disappear with increased camera distance - Rendering - Unreal Engine Forums
It suggests using ‘r.Shadow.RadiusThreshold’ - I didn’t try it at first assuming the project settings option would have the same effect and seeing that they had the same default values of 0.03. In the end I did try with the command line and setting it to a lower value fixed the problem. Are the two settings intentionally different?
