How can I make a hidden object cast shadow?

[SupportiveEntity]

Hey there @dexxxxx420! Welcome to the community! This thread should still work:

Make an object invisible but with shadows

if it is a static object in the world (not a blueprint) select the object go to it’s details panel go to the rendering section set the Actor Hidden In Game flag to true go to the Lighting section set the Cast Hidden Shadow flag to true if it’s in a Blueprint, select the component and do the above in its details panel. Hope this helps!

Though there is another method mentioned in that thread, however it seems that it may have issues with raytracing. I’d give them both a shot just in case!
