How to cast shadow on invisible object ?

Hi, I would like to be able to cast shadows onto an invisible object. Do you know how I could achieve that ? Is it possible to create an invible material with shadows on it ? The light I am using is movable and I am working in UE 4.20

many thanks, Corentin

Need the same!!

is there any chance to do that in UE 5.x?

It seems rally strange to me that there is no way to do that!!

how do you expect this to work? a shadow only has one color. back in 4.x and old school cheats you coulda maybe done it with modulated shadows. unsure about that.

in ue5 you have the shadow pass switch. it only gives you shadows from invisible objects tho. and manages a bit of ao. far from that it not possible to cast shadow onto something that is casting a shadow itself. doesn’t make sense. you know?!? physics. optics. logic. that’s how it works.
