Cast volumetric shadows from animated Light Function

Hey guys!

Im a bit new to UE4 (from houdini) and I was wondering if it was possible to cast volumetric shadows from an animated Light Function, like a gobo.
In the screenshot, I have a light function texture with dots, but the lightrays don’t seem to be affected by the texture. Is there a way to write the light function to the volume?
Basically this video is what I’m going for:
