HI HWNeve, You can reduce the foam density by adjusting the Foam Generation parameters in the FluidSim Actor and the Water Material itself.
Adjust FluidSim Actor Settings:
Select the FluidSim Actor in your scene.
In the Details Panel, find the Foam Settings section.
Tweak the following parameters:
-Foam Intensity: Lower this value to reduce the overall foam density.
-Foam Threshold: Increase this value to make the foam generation more selective, appearing only where the simulation deems necessary.
-Foam Fade Distance: Increase this value to make foam disappear faster at longer distances.
Modify the Water Material Settings (If Using Custom Material):
Open your Water Material Instance if you are using one.
Look for **Foam Generation nodes or parameters.
Adjust:
Foam Opacity: Reduce this value if the foam appears too bright or too prominent.
Density Multiplier: Lowering this value will reduce the amount of foam generated.
