Create a multiple niagara systems for splines in blueprint

Hello,
I’m currently facing an issue with creating multiple Niagara systems for spline components in a Blueprint. I have three spline components (as shown in the attached screenshot), and I’m trying to attach a separate Niagara particle system to each one.

Unfortunately, the particle system only appears on the first spline—nothing shows up on the others. I’ve double-checked the setup, but I can’t seem to figure out what’s going wrong.

If anyone has encountered a similar issue or has any ideas on how to resolve this, I’d greatly appreciate your help. Thanks in advance!

encountered this problem too. Can’t update spline ref inside niagara in runtime. Have you found any solution?
