Niagra Sprite Texture not working

[DoubleBGames]

Hey everyone,
i have created a super basic niagra particle system (in the unreal editor for fortnite)

and now I want to change the material of the sprites to my custom one.

I have set the material to translucent and unlit and it works in the preview and on every mesh I apply it to but when I try it on the niagra sprites I get this error message:

Can anyone please help me with that?
Thanks in advance!

Well that was quick… sometimes you just gotta describe your problem and the solutions comes up immediately…
Anyways the solution was to check the “Use with Niagra Sprites” checkbox in the usage tab of the material.
