Can't cast shadows on Niagara Sprites renderers

Hello there :slight_smile:

I have a question for you. For some reasons, I just can’t make my Niagara Sprite Renderer to cast any shadows. That said, it’s working well with Mesh renderers.

Repro:

  1. In Unreal Version: 5.5.0-37670630+++UE5+Release-5.5, I simply create a new Niagara System using the Fountain template.
  2. Then I create a brand new opaque Lit Material
  3. I’ll assigned this material in my Sprite Renderer
  4. I drag this Niagara System into a new Basic Map
  5. I check Cast Shadows on the Niagara Actor.
  6. I won’t be able to see any shadows casted, but it will work if I apply the default Mesh Renderer

I bet I am missing something obvious here but I can’t figure this out. :thinking:

Thanks in advance for your help :slight_smile:
