making a fake shadow

ah ok…they weren’t showing up and then i read this “We currently only support deferred decals and they only work on static objects.” on the decals info page
what does that mean then?

i have a line trace set up to project the decal. it’s working everywhere except on my moving platforms. the line trace is going to actors, world static and world dynamic.
EDIT - figured it out. just had to make my material a decal material.
thanks for the help!
