Niagara: Custom Alignment Material not showing

Development Asset Creation FX

Hi,

I have a Niagara System using the Sample Static Mesh module and Static Mesh Location.
Particles are spawning properly along the mesh.

All Particles are gone as soon as I change the particle’s material alignment to

  • Custom Alignment
  • Custom Facing Vector

Any idea what is causing this issue?

thanks in advance for any advise
