Liquid filling simulation with Niagara

Technical & Engine Help
#1

Hi everyone,

I’m looking for advice from a fluid simulation expert. I’m working on a level using the Grid3D FLIP Hose template, and I’m trying to animate the water height level in the sequencer, transitioning from 0 to 350 while simultaneously changing its color.

Here’s what I’ve done so far:

  1. Within the Niagara actor, I created a new float user parameter and linked it to the WaterHeight in the Particle Spawn module of the Grid3D_FLIP_FluidControl_Emitter.
  2. I added this parameter through the Niagara component in the sequencer.
  3. I duplicated the master material and its instance from the template and modified the color attributes.

However, controlling the water height level doesn’t seem to work. I’ve successfully added and animated other forces using the same process, but the water height isn’t responding. Additionally, I’m unsure how to add the material attributes from the Niagara emitter into the sequencer.

Any guidance would be greatly appreciated!
