Hi all,

I’m trying to get the particle count of the Grid3D Flip fluid simulation. The number is available on the Details panel in the Niagara editor, but I don’t know who to get that number as a variable.

I found that in the Grid3D_Flip_Hose setup, there’s an exposed parameter: Engine.Emitter.NumParticles

I was able to use it for custom expressions with HLSL rather than blueprint which did what I needed.
