Hi! I’m trying to get a shadow from an object that has “Actor Hidden in Game” turned on. “Hidden Shadow” is also turned on. But it doesn’t appear anyway. I’m sure I had it working at some point before, but it doesn’t anymore. Any ideas on what I might have changed (in settings or somewhere else) in order for it to stop working and how to fix it? Thanks in advance!

I had an issue getting “Hidden Shadow” to work too, my solution ended up being:
- Set top-level actor to
Actor Hidden In Game - Manually setting each aspect of the actor that would cast a shadow to
Hidden Shadow
What to you mean by “top-level actor”?
Top level component, meant top level component 
Like, the root component needs to be set to Hidden
Not working anyway
Same here, in UE 5.0 everything worked ok… now its not working at all… I have topdown project and if character walks inside building hide objects like roof and walls but want them to cast shadow… doestn work in 5.1 
Ok got it to work, Project settings > Rendering > Shadows change to Virtual shadow maps (beta) restart project > follow instruction to enable dx12 settings that engine gives
For me setting Affect Indirect Lighting While Hidden to true worked both in Shadow maps and Virtual Shadow Maps
