Niagara No mesh assigned error

Hi, I’m trying to use niagara to spawn particles from a skeletal mesh. Problem is, when I try to set the skeletal mesh variable it gives a “No mesh assigned error” although I set the “Default Mesh”.

Also this worked in 4.23.1 but stopped working in 4.24

Steps to reproduce:

  1. Create a new project third person template with starter content enabled.

  2. Enable the Niagara and Niagara Extras Plugin

  3. Create a new Niagara Emitter → fountain.

  4. Create a skeletal mesh variable under Particles.

  5. Assign the SK_Mannequin skeletal mesh as “Default Mesh”.

  6. Gives a “No mesh assigned error”

I also filed a bug report, but wanted to ask if someone might happen to know a workaround (my goal is to spawn particles on the skeletal mesh triangles using niagara).

Hello, I’m having the exact same issue, did you have any luck solving this problem? I have been searching everywere for some clues on how to solve this but so far no luck…

No, I didn’t solve it. You could look at the content examples though. Open the niagara map and take a look at 3.3 skeletal mesh reproduction. There it’s apparently working (but I don’t need this feature right now, so I didn’t spend my time looking at it, so I can’t tell you whether or not this will solve the issue).
